Hi, Our hbase/hadoop servers machines were shutdown without bringing the hadoop and hbase services down properly.Now when we try to bring up hbase we get the following error in the master log:
org.apache.hadoop.hbase.NotServingRegionException: Region is not online: -ROOT-,,0 Hadoop services (namenode,jobtracker,datanode etc) have come up properly and we are able to see the files in HDFS. But HBase Master keeps on throwing this exception and then finally throws a Java Heap Space error. Note: We have two datanodes, replication set to 2 and around 900 blocks are shown as under-replicated. --------------------------------- Thanks & Regards Himanish
