HBase Failed to Start Due to Inappropriate Parameter Settings

Symptom

After some parameters are modified, HBase cannot be started.

Cause Analysis

1. Check the HMaster log (/var/log/Bigdata/hbase/hm/hbase-omm-xxx.log). It is found that the total of hbase.regionserver.global.memstore.size and hfile.block.cache.size is greater than 0.8, which causes the startup failure. Therefore, adjust the parameter values to make sure that the total value is less than 0.8.

   

2. Check the HMaster and RegionServer out logs (/var/log/Bigdata/hbase/hm/hbase-omm-xxx.out/var/log/Bigdata/hbase/rs/hbase-omm-xxx.out). It is found that Unrecognized VM option is displayed.

   Unrecognized VM option 
   Error: Could not create the Java Virtual Machine.
   Error: A fatal exception has occurred. Program will exit.

   Check the GC_OPTS parameters. It is found that the parameters contain unnecessary spaces, for example, -D sun.rmi.dgc.server.gcInterval=0x7FFFFFFFFFFFFFE.

Solution

1. After the MemStore and cache parameters are modified, the HBase service is restarted successfully.
2. After the GC_OPTS parameters are modified, the HBase service is restarted successfully.
