Ivan Veselovsky commented on IGNITE-482:
----------------------------------------

With Hadoop 2.4.1 (BigTop 0.8.0) these exceptions sometimes have message like "org.apache.hadoop.HadoopIllegalArgumentException:
Cannot close proxy - is not Closeable or does not provide closeable invocation handler class
com.sun.proxy.$Proxy68 "
