Summary: [AMv2] Corrupt Procedure WAL file; procedure data stored
out of order
Key: HBASE-18152
URL: https://issues.apache.org/jira/browse/HBASE-18152
Project: HBase
Issue Type: Bug
Components: Region Assignment
Affects Versions: 2.0.0
Reporter: stack
Assignee: stack
Priority: Critical
Fix For: 2.0.0
I've seen corruption from time-to-time testing. Its rare enough. Often we can
get over it but sometimes we can't. It took me a while to capture an instance
of corruption. Turns out we are write to the WAL out-of-order which undoes a
basic tenet; that WAL content is ordered in line w/ execution.
Below I'll post a corrupt WAL.
Looking at the write-side, there is a lot going on. I'm not clear on how we
could write out of order. Will try and get more insight. Meantime parking this
issue here to fill data into.
