stack commented on HBASE-12978: ------------------------------- The file just previous to this one -- the result of a compaction on meta -- seems fine. Looking at its indices, I see stuff like this: key=IntegrationTestBigLinkedList,C//LATEST_TIMESTAMP/Maximum offset=166171, dataSize=8247 ... so this looks like our index entry 'tightener', the code that shrinks the keys so take up less space in index. The problematic one is this: key=IntegrationTestBigLinkedList,,//LATEST_TIMESTAMP/Maximum offset=116101, dataSize=8298 ... which has the double ',,' in it which has special meaning for our meta table comparators..... > hbase:meta has a row missing hregioninfo and it causes my long-running job to > fail > ---------------------------------------------------------------------------------- > > Key: HBASE-12978 > URL: https://issues.apache.org/jira/browse/HBASE-12978 > Project: HBase > Issue Type: Bug > Reporter: stack > Fix For: 1.0.1 > > Attachments: e7cadabc6e5e46c7bf6b3d445f0c53cf > > > Testing 1.0.0 trying long-running tests. > A row in hbase:meta was missing its HRI entry. It caused the job to fail. > Around the time of the first task failure, there are balances of the > hbase:meta region and it was on a server that crashed. I tried to look at > what happened around time of our writing hbase:meta and I ran into another > issue; 20 logs of 256MBs filled with WrongRegionException written over a > minute or two. The actual update of hbase:meta was not in the logs, it'd been > rotated off. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
