hbase数据查不到,小松鼠客户端连接不上,hbase shell扫描报错部分日志:

ERROR: org.apache.hadoop.hbase.exceptions.RegionOpeningException: Region ADVICE,,1484647165178.b827fafe905eda29996dfb56bd9fd61f. is opening on hadoop79,60020,1497005577348

Region EHRMAIN,,1489599097179.61688929e93c5143efbe19b68f995c76. is not online on hadoop79,60020,1497002696781

phoenix报错:is opening on hadoop78,60020

命令hbase hbck:出现大量异常信息

解决办法:关掉hbase集群,在每个RegionServer上的hbase-site.xml配置文件里面增加如下

hbase.regionserver.executor.openregion.threads

100

重启hbase集群,命令hbase hbck:Summary:

Table CONSULTATIONRECORD is okay.

    Number of regions: 6

    Deployed on:  hadoop76,60020,1497006965624 hadoop77,60020,1497006965687 hadoop78,60020,1497006965700 hadoop79,60020,1497006965677

Table PT_LABREPORT is okay.所有表都ok。

注:hbase hbck -fix可以修复hbase数据不一致
