Denys Vergiles created HBASE-19314: -------------------------------------- Summary: Column family with name "=" cause region in transition Key: HBASE-19314 URL: https://issues.apache.org/jira/browse/HBASE-19314 Project: HBase Issue Type: Bug Components: Region Assignment Affects Versions: 1.2.0 Environment: Server - AWS r4.2xlarge - 8 cores, 60 Gb RAM OS - CentOS 7 Java - 1.8.0_121 HBase Version 1.2.0
Reporter: Denys Vergiles During alter operation with namespaces i was able to create new column family with name '='. I didn't find any restriction in setting column name to non-alphabetical sign. Once column name is created, master server is fails to start due to infinite transition status of region server The only possible solution which i found was to delete broken column families. On attempt to clear status of all ephemeral nodes in zookeeper, did not allow to bring server back to life (https://community.cloudera.com/t5/Storage-Random-Access-HDFS/HBase-Region-in-Transition/m-p/26727#M1183) hbase hbck {code} 17/11/14 13:31:16 INFO util.HBaseFsck: Handling overlap merges in parallel. set hbasefsck.overlap.merge.parallel to false to run serially.
