Raghu Angadi commented on HADOOP-5116:
--------------------------------------
The stacktrace shows that test is blocked inside a write() to a pipe. This
write is supposed to be non-blocking. Is it possible that either JVM or AIX
ignores {{channel.configureBlocking(false)}} for pipes?
Could you check if this process is busy during this time? It it is then then
there could be other possibilities.
