It would be nice if you can isolate the use case that triggers the issue so that we can reproduce. You could also hit HBASE-6479 if you still have HFileV1 files around. J-D On Sun, May 5, 2013 at 10:49 PM, Viral Bajaria viral.baja...@gmail.comwrote: On Sun, May 5, 2013 at 10:45 PM,

Cached an already cached block (HBASE-5285)

2013-05-05 Thread Viral Bajaria
Hi, I have been consistently hitting the following error in one of my QA clusters. I came across two JIRAs, the first one (HBASE-3466) was closed saying Cannot Reproduce but a new one was re-opened under HBASE-5285. I am using HBase 0.94.4 and Hadoop 1.0.4 24 region servers (8 cores, 8GB RAM)

Just to confirm you are getting this with LruBlockCache? If with LruBlockCache then the issue is critical. Because we have faced similar issue with OffHeapCache. But that is not yet stable as far as i know. Regards Ram On Mon, May 6, 2013 at 10:45 AM, Viral Bajaria
