Wei-Chiu Chuang commented on HBASE-20145: ----------------------------------------- Posted a patch to log additional messages when 1. the stream class does not implement StreamCapabilities, 2. the result of StreamCapabilities test. Log the output stream class and the associated wrapped stream class. The 2nd item will be useful when troubleshooting hbase problem on a HDFS erasure coded cluster. > HMaster start fails with IllegalStateException when HADOOP_HOME is set > ---------------------------------------------------------------------- > > Key: HBASE-20145 > URL: https://issues.apache.org/jira/browse/HBASE-20145 > Project: HBase > Issue Type: Bug > Environment: HBase-2.0-beta1. > Hadoop trunk version. > java version "1.8.0_144" > Reporter: Rohith Sharma K S > Assignee: Wei-Chiu Chuang > Priority: Critical > Attachments: HBASE-20145.master.001.patch > > > It is observed that HMaster start is failed when HADOOP_HOME is set as env > while starting HMaster.
