[jira] [Reopened] (HBASE-25449) 'dfs.client.read.shortcircuit' should not be set in hbase-default.xml

["Duo Zhang (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-25449?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Duo Zhang reopened HBASE-25449:
-------------------------------

This breaks a lot of UTs.

Seems the MiniHDFSCluster can not load correct configs and then when running different UTs conurrectly, there will be conflicts on the shared resources.

Will revert it from all active branchs, please re-apply after fixing the problem.

Thanks.

> I think this parameter is not suitable for in hbase-default.xml, because in this case, HDFS explicitly set to "dfs.client.read.shortcircuit=true", hbase rely on HDFS configuration, the parameters in hbase service still is false.Must be explicitly in hbase-site.xml is set to "dfs.client.read.shortcircuit=true" to take effect.
