Hudson commented on HBASE-14201: -------------------------------- FAILURE: Integrated in HBase-1.2 #103 (See [https://builds.apache.org/job/HBase-1.2/103/]) HBASE-14201 hbck should not take a lock unless fixing errors (eclark: rev 25bf721b517b7740821dbffc5f7c7b5c539e9aca) * hbase-server/src/test/java/org/apache/hadoop/hbase/util/hbck/HbckTestingUtil.java * hbase-server/src/test/java/org/apache/hadoop/hbase/util/TestHBaseFsck.java * hbase-server/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java > hbck should not take a lock unless fixing errors > ------------------------------------------------ > > Key: HBASE-14201 > URL: https://issues.apache.org/jira/browse/HBASE-14201 > Project: HBase > Issue Type: Bug > Components: hbck, util > Affects Versions: 2.0.0, 1.3.0 > Reporter: Simon Law > Assignee: Simon Law > Fix For: 2.0.0, 1.2.0 > > Attachments: HBASE-14201-v0.patch, HBASE-14201-v1.patch > > > By default, hbck is run in a read-only checker mode. In this case, it is > sensible to let others run. By default, the balancer is left alone, > which may cause spurious errors, but cannot leave the balancer in a bad > state. It is dangerous to leave the balancer by accident, so it is only > ever enabled after fixing, it will never be forced off because of > racing. > When hbck is run in fixer mode, it must take an exclusive lock and > disable the balancer, or all havoc will break loose. > If you want to stop hbck from running in parallel, the -exclusive flag > will create the lock file. If you want to force -disableBalancer, that > option is available too. This makes more semantic sense than -noLock and > -noSwitchBalancer, respectively. > This task is related to HBASE-14092. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
