  • Hbase常见异常

    1、 HBase is able to connect to ZooKeeper but the connection closes immediately

    hbase(main):001:0> list

    TABLE                                                                           

    ERROR: org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is able to connect to ZooKeeper but the connection closes immediately. This could be a sign that the server has too many connections (30 is the default). Consider inspecting your ZK server logs for that error and then make sure you are reusing HBaseConfiguration as often as you can. See HTable's javadoc for more information.

    Here is some help for this command:
    List all tables in hbase. Optional regular expression parameter could
    be used to filter the output. Examples:
      hbase> list
      hbase> list 'abc.*'

    hbase(main):002:0> exit

    解决方法:
    修改/etc/hosts:
    #127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    #::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    将原有的前2行去掉。
