Subject Out of Memory Error - Plz suggest if a JIRA needs to be created
Date Wed, 08 Aug 2012 14:26:34 GMT
Hi All,

I am currently using HCatalog 0.4 with PIG 0.9.2.

After 3 or 4 days, I encountered PIG exceptions and digging deep I found
that it tries to connect to HCatalog server and gets socket read timeout.

Looking at the JVM process of Hcatalog server suggest OOM. I have attached
the jstat details for further reference.

At this point in time, I am not sure which usecase causes this OOM. I would
post more details as and when I find. Should I raise a JIRA for this?. Plz
suggest.

[rajesh@machineXYZ hcatalog]$ sudo  /usr/java/jdk1.6.0_25/bin/jstat -gcutil
