can you check whether your master is running or not? ERROR: Can't get master address from ZooKeeper; znode data == null

can you try with below command sqoop import-all-tables --connect jdbc:mysql://mysql_server/mysql_table --table mysql_table_name --hbase-table hbase_table_name --column-family metadata --hbase-create-table --username root -P

Yes, sqoop considers split-by column(--split-by <column-name>) as the rowkey if --hbase-row-key is not specified.

Hbase is a key value store so it will require any one col to be declared as row key. can you share the schema of sqllserver and how you want it to look in hbase?

Hi @Raghu Gurrala, Would you mind taking a look of below page. http://www.theshell.guru/native-memory-allocation-mmap-failed-to-map-xx-bytes-for-committing-reserved-memory-jdk-1-8-centos-6-7/ This guy also faced the same problem and I think he has the working fix.

No Sunile, currently phoenix doesn't support creating custom coprocessors endpoints and calling them using a sql construct.

It seems , we can do in same way for squirrel. http://stackoverflow.com/questions/23770235/squirrel-sql-exception-logging JFYI , sqlline can also be used as a remote client.

Modify PHOENIX_HOME/bin/log4j.properties to log DEBUG/INFO in logs or console. It will log in current_path/psql.log psql.root.logger=DEBUG,console,DRFA log4j.threshold=DEBUG And, sqlline.py expects log4j.properties in current path (from where you are running the sqlline)

Look at Option 1 on below post. https://community.hortonworks.com/questions/27312/hbase-shell-is-throwing-corruptedsnapshotexception.html#answer-27318

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/path/hbase<version>.jar run /etc/hbase/conf/hbase-env.sh And, echo $HADOOP_CLASSPATH and check all the required hbase jars are there. Then, java -cp $HADOOP_CLASSPATH:applicationJar package.class
