--------------------------------------
[~vozerov], I fixed the hadoop suite run (please take a look at the [tests
results|https://ci.ignite.apache.org/viewType.html?buildTypeId=IgniteTests24Java8_Hadoop&branch_IgniteTests24Java8=pull%2F5003%2Fhead&tab=buildTypeStatusDiv]),
but the fix isn't in scope H2 lazy patch.
I guess the root cause is:
{{HadoopClassLoader}} implementation & hadoop helper produce memory leaks (e.g.
{{GridKernalContext}}). And H2 lazy patch add the last critical allocates for
one instance of {{GridKernalContext}} because connection pool was changed etc.
The patch for this problem doesn't solve all leaks in the hadoop module but
reduce them.
Please review the draft of the patch. I'll fix cosmetics if you agree in
general.
