Description

test HadoopCommandLineTest.testHiveCommandLine reproducibly fails due to failed assertion:

problem is that org.apache.ignite.internal.processors.hadoop.impl.v2.HadoopV2TaskContext is loaded by the Job class loader if the class loader is "shared" (see org.apache.ignite.internal.processors.hadoop.HadoopJobProperty#JOB_SHARED_CLASSLOADER), and this is true by default. But the assertion in the test expects this to be task class loader, what can be true, but is false by default.
