Nasser Ebrahim commented on HDFS-9475:
--------------------------------------
Hi Rakesh,
We are interested to know whether this problem still exists with the latest
level of IBM JDK 8. We are happy to analyze the issue if it still exists. In
that case, we have couple of more questions to understand the issue better.
- Whether the issue occurred only with s390x linux or it can be recreatable
with intel/power architecture of linux.
- If the problem is recreatable with other architectures of linux, whether the
problem is recreatable with openJDK or Oracle JDK 8?.
Thank you,
Nasser Ebrahim
