Facing a new problem again. Each time i start hbase and try to create a table on hbase shell, i see
hbase(main):002:0> create 'student', 'marks' ERROR: org.apache.hadoop.hbase.PleaseHoldException: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing I guessed some administrative work is in progress and noticed the http://<hostname>:60010 (hbase master web UI). For so much time i observe the below status and not able to stop the hbase also during this time. Start Time Description State Status Mon Aug 26 11:35:21 IST 2013 Master startup RUNNING (since 15mins, 47sec ago) Submit log splitting work of non-meta region servers (since 15mins, 38sec ago) Is some thing to do with the below property? I have commented and uncommented the below property in my hbase-site.xml, still i see the same thing in both cases. <property> <name>hbase.master.distributed.log.splitting</name> <value>true</value> </property> In master log, i don't see any thing wrong, except below line when i searched with a string 'error'. 2013-08-26 11:35:22,463 ERROR org.apache.hadoop.hbase.regionserver.metrics.SchemaMetrics: Inconsistent configuration. Previous configuration for using table name in metrics: true, new configuration: false 2013-08-26 11:35:22,467 DEBUG org.apache.hadoop.hbase.io.hfile.HFileWriterV2: Initialized with CacheConfig:disabled . . . (I don't know whether the above line has got some significant effect.) Could any one help..
