[jira] [Created] (HBASE-23669) ZNodeClearer#clear() throws
IllegalArgumentException
kangkang.guo created HBASE-23669:
------------------------------------
Summary: ZNodeClearer#clear() throws IllegalArgumentException
Key: HBASE-23669
URL: https://issues.apache.org/jira/browse/HBASE-23669
Project: HBase
Issue Type: Bug
Affects Versions: 2.1.5
Reporter: kangkang.guo
Assignee: kangkang.guo
Precondition:
hbase.balancer.tablesOnMaster = true
hbase.balancer.tablesOnMaster.systemTablesOnly = true
In case of master-rs collocation HBASE_ZNODE_FILE is overwritten by regionserver process in HRegionServer#handleReportForDutyResponse() here is how it looks on master server:
[hadoop@master-node data]$ cat hbase-hadoop-master.znode
/hbase/rs/master-node,16000,1578371505720
When ZNodeClearer#clear(), the rsZNode is also splicing with the contents of the file, causing an exception：
java.lang.IllegalArgumentException: Invalid path string "/hbase/rs//hbase/rs/master-node,16000,1578371503003" caused by empty node name specified @10
