Dear all, After searching on the Web and asking for help from friends, I noticed that the pseudo distributed configuration in the book, HBase the Definitive Guide, was not complete. Now the ZooKeeper related exception is fixed. However, I got another error when typing "status" in the HBase shell.
ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 Times I am trying to fix it myself. Your help is highly appreciated. Thanks so much!
