[jira] [Updated] (HBASE-6050) HLogSplitter renaming recovered.edits and CJ removing the parent directory races, making the HBCK to think cluster is inconsistent.

Pls provide your comments. HLogSplitter renaming recovered.edits and CJ removing the parent directory races, making the HBCK to think cluster is inconsistent. --- Key: HBASE-6050 URL: https://issues.apache.org/jira/browse/HBASE-6050 Project: HBase Issue Type: Bug Reporter: ramkrishna.s.vasudevan Attachments: HBASE-6050.patch The scenario is like this - A region is getting splitted. - The master is still not processed the split . - Region server goes down. - Split log manager starts splitting the logs and creates the recovered.edits in the splitlog path. - CJ starts and deletes the entry from META and also just completes the deletion of the region dir. - in hlogSplitter on final step we rename the recovered.edits to come under the regiondir. There if the regiondir doesnot exist we tend to create and then add the recovered.edits. Because of this HBCK thinks it to be an orphan region because we have the regiondir but with no regioninfo. Ideally cluster is fine but we it is misleading. {code} } else { Path dstdir = dst.getParent(); if (!fs.exists(dstdir)) { if (!fs.mkdirs(dstdir)) LOG.warn(mkdir failed on + dstdir); } } fs.rename(src, dst); LOG.debug( moved + src + = + dst); } else { LOG.debug(Could not move recovered edits from + src + as it doesn't exist); } } archiveLogs(null, corruptedLogs, processedLogs, oldLogDir, fs, conf); {code} -- This message is automatically generated by JIRA.
