[DISCUSSION] Urgent Ignite bug fix release

[dmagda]

Igniters,

Presently every Apache Ignite node requests 80% of RAM from an operating system. We debated a lot about this default [1] and as a practice shows those who voted for the lower value (20%-25%) were right.

Our users started reporting about bizarre issues ([2], [3], [4]) when a cluster hangs, freezes for a while or even crashes during standard preloading phase or minor workloads.

It’s turned out to be that lack of RAM causes extensive swapping and checkpointing activity. Even more, the issue can be reproduced on your laptop if you launch a couple of nodes and start data preloading.

All this can be avoided if you allocated less than 80% and tune the checkpointing if the persistence is used. Unfortunately, only few could get to this point, the rest would kick Ignite out from their deployments.

Thus, we have to fix the defaults ([5] and [6]) on our own and release an emergency release with the fixes as soon as possible.

Any objections or other thoughts?

Let's include to the release tickets with optimizations of checkpointing
algorithm:

https://issues.apache.org/jira/browse/IGNITE-6178
https://issues.apache.org/jira/browse/IGNITE-6033
https://issues.apache.org/jira/browse/IGNITE-5961

This will help users who are experiencing problems with slow checkpoints.

Also, let's include https://issues.apache.org/jira/browse/IGNITE-6183 to
soften "Ignite node crashed in the middle of checkpoint" message as per
discussion
<http://apache-ignite-developers.2346864.n4.nabble.com/Ignite-close-G-stop-name-true-Change-flag-cancel-to-false-td20473.html>.

Igor, I would change the message. How about this:

Required RAM size is larger than total physical memory available for OS.
> Please change MemoryConfiguration.WhichProperty and

Also, can we calculate what the memory size allocated for each node should
be? In that case we should suggest it.

I suppose we should not forget JVM heap size and suggest to reduce both
options

Igor, what is this flood of WARN messaging coming after the text? Are we
really going to print this whole thing out?

The message without logging layout:

Not enough memory for current process [required=29251MB, available=15942MB].
Please change MemoryConfiguration.systemCacheMaxSize and
MemoryConfiguration.defaultMemoryPolicySize to decrease memory allocated
for each node.

Current settings:
   HeapInit=250MB
   HeapMax=3543MB
   DefaultMemoryPolicySize=12753MB
   SystemCacheInitialSize=40MB
   SystemCacheMaxSize=100MB

Other ignite instanses on the server require: 12853MB

I think it's make sense to describe what these numbers are consist of.

We simple say which parameters have an impact on how much memory the
instance needs and their (parameters) actual values.

Also we notice that more than one Ignite instance are ran on the server or
workstation and it also consumes memory.

Igor,

Let me suggest this format.

---------------------------------------------
Excessive memory usage by Ignite node process (performance may drop) [requested=29251MB, available=15942MB]

Please tune the following settings:
  [MemoryConfiguration.defaultMemoryPolicySize = suggested value]
  MemoryConfiguration.systemCacheMaxSize = suggested value
  [MemoryPolicyConfiguration.maxSize for {policy_name_1} = suggested value]
  [MemoryPolicyConfiguration.maxSize for {policy_name_2} = suggested value]

Current settings:
   [DefaultMemoryPolicySize = value]
   [{policy_name_1} size = value]
   [{policy_name_1} size = value]
   SystemCacheInitialSize = value
   SystemCacheMaxSize = value
   Java Heap Init Size = value
   Java Heap Max Size = value

The overall memory usage by all Ignite nodes on the host: value
-------------------------------------------

Records in […] are optional. If custom memory policy is not set or the default memory policy is overridden the output will miss some of the rows.

As for systemCacheMaxSize, it should be show ONLY if the parameter was set explicitly by user code. Otherwise, the platform should be wise enough to instantiate it properly depending on the host memory usage.

[dsetrakyan]

I like the format proposed by Denis, very clear.

However, I also do not understand why a user should change the size of some
system cache. How would a user ever know what value to put there? This
value should be configured by Ignite automatically.

Guys,

ML lib profile is missing in 2.1 release! That must be fixed and rolled out in this emergency release:
https://issues.apache.org/jira/browse/IGNITE-6193 <https://issues.apache.org/jira/browse/IGNITE-6193>

Oleg, Yuri, please step in and handle the issue.

BTW, who is considered to be the release manager of this release?

Denis

One more example of possible warning:

-----------------------------------------------------
Excessive memory usage by Ignite node process (performance may drop)
[requested=44613MB, available=15942MB].

Please tune the folowing settings as suggested:
  MemoryPolicyConfiguration.initialSize for bigPlc: 8102MB
  MemoryPolicyConfiguration.maxSize     for bigPlc: 8102MB
  MemoryPolicyConfiguration.initialSize for dfltPlc: 100MB
  MemoryPolicyConfiguration.maxSize     for dfltPlc: 100MB

Current settings:
  Java Heap  maxSize: 3543MB
  Java Heap initSize: 250MB
  MemoryPolicyConfiguration.initialSize for bigPlc: 256MB
  MemoryPolicyConfiguration.maxSize     for bigPlc: 40960MB
  MemoryPolicyConfiguration.initialSize for dfltPlc: 10MB
  MemoryPolicyConfiguration.maxSize     for dfltPlc: 10MB
  The overall expected memory usage by all Ignite nodes on the host: 44613MB
-----------------------------------------------------

[dsetrakyan]

Looks good, but why in the example provided are we suggesting 8GB? 2 nodes
with 8GB will completely exhaust the available memory. I would suggest 6 or
7GB.

Also, why 100MB for default policy. Anything under 1GB seems too small.

Can you please comment?

The suggestion here is based on initial settings, and it's so because there
is no other nodes on the host in the example.

The algorithm tries to preserve the original ratio of memory policies
keeping numbers reasonable (for example after some thresshold it will
suggest not to use several memory policies if there is not enough of memory
for all of them) and taking into consideration nodes count on the host,
each jvm heap, needed memory for OS, etc

Ok, the check happens at the node start time or on NODE_JOIN event

in general it looks like:

1) calculate expected used memory = heap max + system cache max + all
custom policies max + default policy size and put it into a node attribute

2) get total physycal memory, calculate expected safe to be used memory
amount (leave 4 gb min or 20% of available memory for OS)

3) if expected used memory + expected used memory of other nodes on the
host > than safe to be used memory amount, start calculating suggestions

4) Each ignite instance needs at least 512mb heap + 40mb system cache +
100mb default polycy, if available memory is less we cannot suggest
anything reasonable, print warning, stop calculation.

5) check heap size (shouldn't exceed 30% of available memory (total_memory
- reserved for OS memory) * 30% for all JVMs, if it exeedes, suggest just
calculated value or 512MB minimal)

6) check if system cache size changed, suggest default value if it's so

7) in case 100 mb * policies count < available memory, suggest using
default policy with max size equals to remaining memory (available - heap -
system cache)

8) calculate new size for each memory policy ( it's user defined size *
(remaining / (all_policies_size * nodes_cnt)); in proportion to
remaining memory, devided by nodes number on the host or 100 mb minimal)

9) print suggestions
