            Assignee: Ivan Veselovsky
            Priority: Minor

FileSystem is taken as a local variable and used in the following methods.
Need to check if we should do that as try (FileSystem fs = ...) { ... }, of use the Fs without closing.

1) org.apache.ignite.internal.processors.hadoop.v2.HadoopV2JobResourceManager#cleanupStagingDirectory
2) org.apache.ignite.internal.processors.hadoop.v2.HadoopV2JobResourceManager#processFiles

3) org.apache.ignite.internal.processors.hadoop.v2.HadoopV2JobResourceManager#prepareJobEnvironment

4) org.apache.ignite.hadoop.fs.IgniteHadoopFileSystemCounterWriter#write
