Elliott Clark commented on HBASE-14317: --------------------------------------- Yeah the actual patch isn't too bad. I just hope that it doesn't obscure the reason why we're getting stuck. > Stuck FSHLog: bad disk (HDFS-8960) and can't roll WAL > ----------------------------------------------------- > > Key: HBASE-14317 > URL: https://issues.apache.org/jira/browse/HBASE-14317 > Project: HBase > Issue Type: Bug > Affects Versions: 1.2.0, 1.1.1 > Reporter: stack > Priority: Critical > Attachments: HBASE-14317.patch, [Java] RS stuck on WAL sync to a dead > DN - Pastebin.com.html, raw.php, subset.of.rs.log > > > hbase-1.1.1 and hadoop-2.7.1 > We try to roll logs because can't append (See HDFS-8960) but we get stuck. > See attached thread dump and associated log. What is interesting is that > syncers are waiting to take syncs to run and at same time we want to flush so > we are waiting on a safe point but there seems to be nothing in our ring > buffer; did we go to roll log and not add safe point sync to clear out > ringbuffer? > Needs a bit of study.
