Answer 1

You need to increase the below hbase configuration property to a higher value in hbase server and client configurations, default value is 1 min(60000 Milli Sec)

  <property>
    <name>hbase.rpc.timeout</name>
    <value>600000</value>
  </property>

The most important thing is that the below command should return the correct hbase config directory where hbase-site.xml file contains the above property. If the value of hbase_conf_path is empty or ., Execute the command export HADOOP_CONF_DIR=<correct_hbase_dir>; for pointing to correct hbase configuration before executing the command sqlline.py.

phoenix_utils.py  | grep hbase_conf_path
