Re: Hmaster starting issue.

2023-06-07 Thread Duo Zhang
Do you want to start a single node pseudo distributed hbase cluster, or a
fully distributed cluster?

For the former one, you do not need to start hdfs or zookeeper, just type
./start-hbase.sh with default configuration is enough. If you want a fully
distributed cluster, and want it to use pre deployed zookeeper and HDFS,
please read this section in our ref guide.

https://hbase.apache.org/book.html#standalone_dist

And make sure you have subscribed to the user@hbase or user-zh@hbase
mailing list otherwise you may not receive the response.

Thanks.

configuration when I'm starting start-hbase.sh on mastr node i'm able to
see this.
jps
15299 Jps
13764 NameNode
14981 HMaster
14296 ResourceManager
15177 HRegionServer
14876 HQuorumPeer
14063 SecondaryNameNode
but after going into shell if i'm creating some table it is giving me error
of *ERROR: KeeperErrorCode = NoNode for /hbase/master.*
Can you help me how to start hbase.
