@Ivan Majnaric, There is no harm in running sqlline.py again. Actually it is a client to query phoenix. It will create the SYSTEM tables if not already created. You can check this answer by Josh in the link. https://community.hortonworks.com/questions/64005/phoenix-security-and-initial-system-table-creation.html If this works for you please mark the answer as accepted so that it will be useful for the community. Thanks, Aditya ... View more

For HDP 2.3 (Apache 1.1.2), ./hbase-common/src/main/java/org/apache/hadoop/hbase/HBaseConfiguration.java calls HeapMemorySizeUtil.checkForClusterFreeMemoryLimit(conf); There is no HBaseConfiguration.checkForClusterFreeMemoryLimit Can you double check your classpath to see which hbase related jars are present. Please pastebin those jars Thanks ... View more

It was DHCP failing to see a response from the DHCP server for periods of time. d2 Ubuntu(14.04) instances were using Enhanced Networking and the "ixgbevf" driver 2.11.3-k. 2.11.3-k is below the minimum recommended version 2.14.2 and should be upgraded to 2.16.4. We upgraded the driver to the latest version which seems to have fixed the issue. Reference: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/sriov-networking.html#enhanced-networking-ubuntu ...
