esahekmat commented on issue #1902: HDFS-15219. fix ResponseProcessor.run to catch Throwable instead of Exception
URL: https://github.com/apache/hadoop/pull/1902#issuecomment-601901409
 
 
   I tried, but as ResponseProcessor class is a private inner class it's almost impossible to mock its behavior ( throw Error in the middle of run() method)
   even I tried to mock block field to throw an Error when calling setNumBytes(), but as it's final and ExtendedBlock and BlockToWrite classes are very cautious to not expose their internal object it is impossible to inject my mock instead of their Block object.
   can you help me to find a way to write its unit test?
