Lars Hofhansl commented on HBASE-5153: -------------------------------------- Also it occurred to me that another nice change would be to be able specify the retry count for resetZooKeeperTrackersWithRetries different from the other operations. The thinking is this: While the ZK is not reachable the HConnection (and any other HConnection) is essentially not usable. In some settings it might be good to have the connection just sit there, and retry until the connection is bad. Maybe for another jira. Where are we with this generally? Is it just TestMergeTool hanging? If so I'll have a look at it today. > Add retry logic in HConnectionImplementation#resetZooKeeperTrackers > ------------------------------------------------------------------- > > Key: HBASE-5153 > URL: https://issues.apache.org/jira/browse/HBASE-5153 > Project: HBase > Issue Type: Bug > Components: client > Affects Versions: 0.90.4 > Reporter: Jieshan Bean > Assignee: Jieshan Bean > Fix For: 0.94.0, 0.90.6, 0.92.1 > > Attachments: 5153-92.txt, 5153-trunk.txt, 5153-trunk.txt, > HBASE-5153-V2.patch, HBASE-5153-V3.patch, HBASE-5153-V4-90.patch, > HBASE-5153-V5-90.patch, HBASE-5153-V6-90-minorchange.patch, > HBASE-5153-V6-90.txt, HBASE-5153-trunk-v2.patch, HBASE-5153-trunk.patch, > HBASE-5153.patch, TestResults-hbase5153.out > > > HBASE-4893 is related to this issue. In that issue, we know, if multi-threads > share a same connection, once this connection got abort in one thread, the > other threads will got a > "HConnectionManager$HConnectionImplementation@18fb1f7 closed" exception. > It solve the problem of "stale connection can't removed". But the orignal > HTable instance cann't be continue to use. The connection in HTable should be > recreated. > Actually, there's two aproach to solve this: > 1. In user code, once catch an IOE, close connection and re-create HTable > instance. We can use this as a workaround. > 2. In HBase Client side, catch this exception, and re-create connection. -- This message is automatically generated by JIRA.
