Lei Chen created HBASE-21706: -------------------------------- Summary: Inconsistency of fs.defaultFS between active and standby masters Key: HBASE-21706 URL: https://issues.apache.org/jira/browse/HBASE-21706 Project: HBase Issue Type: Bug Components: conf, master Affects Versions: 1.1.2 Reporter: Lei Chen
I'm using HDP-2.3.6.22-1 with HBase HA configured. I noticed that active and standby masters have different `fs.defaultFS` on their /conf pages. Given `fs.defaultFS` is set to <scheme>:<authority> and `hbase.rootdir` is set to <scheme>:<authority>/<root-dir> in core-site.xml on all the hosts, it looks like standby masters has `fs.defaultFS` programatically set to the same value as `hbase.rootdir`. For example, on a 3 heads cluster DEV-CLUSTER, my active master has the following line on the /conf page {code:java} <property><name>fs.defaultFS</name><value>hdfs://DEV-CLUSTER</value><source>programatically</source></property> {code} but standby masters has {code:java} <property><name>fs.defaultFS</name><value>hdfs://DEV-CLUSTER/hbase-root</value><source>programatically</source></property>{code} Please correct me if this is not a bug but a feature, but I find this behavior surprising plus I cannot locate any related document. >From a quick looking at the code, the cause seems to be that standby masters >got the property set in >[HRegionServer.java|https://github.com/hortonworks/hbase-release/blob/HDP-2.6.3.22-tag/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java#L649-L652], > and active master got it set in a different way in >[MasterFileSystem.java|https://github.com/hortonworks/hbase-release/blob/HDP-2.6.3.22-tag/hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterFileSystem.java#L132-L137]. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
