I've setup an Accumulo 1.6 cluster with Hadoop 2.4.0 (with a secondary namenode). I wanted to convert the secondary namenode to be a standby (hence HDFS HA).
After getting HDFS HA up and making sure the hadoop configuration files were accessible by Accumulo, I started up Accumulo. I noticed some reports of tablet servers failing to connect, however, they were failing to connect to HDFS over port 9000. That port is not configured/used with HDFS HA so I'm unsure why they are still trying to talk to HDFS using the old configuration. Any thoughts ideas? I know Accumulo 1.6 works with HDFS HA, but I'm curious if the tests have ever been run against a non-HA cluster that was converted to HA (with data in it). -- https://github.com/mindscratch https://www.google.com/+CraigWickesser https://twitter.com/mind_scratch https://twitter.com/craig_links
