Hbase建表时遇到的问题This could be a sign that the server has too many connections

Hbase创建表时遇到以下错误：

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.
