I believe the problem that you are running into is that because dfs.default.uri was not specified, then fs.defaultFS was used to write entries to the accumulo.root and accumulo.metadata tables. Suggest doing the following:
Update to the latest version of Accumulo 1.6.1-SNAPSHOT set instance.dfs.uri to: hdfs://mycluster set instance.volumes to: hdfs://mycluster set instance.volumes.replacements to: hdfs://somehostname:9000/accumulo hdfs://mycluster/accumulo ----- Original Message ----- From: "craig w" <[email protected]> To: [email protected] Sent: Friday, August 8, 2014 9:13:02 AM Subject: Re: accumulo 1.6 and HDFS non-HA conversion to HDFS HA In $HADOOP_CONF_DIR/core-site.xml I used to have: <property> <name> fs.default.name </name> <value>hdfs://somehostname:9000</value> </property> When going to HDFS HA, I removed that property and have: <property> <name>fs.defaultFS</name> <value>hdfs://mycluster</value> </property> In the accumulo-site.xml I don't have instance.volumes or instance.dfs.uri.

If so, you may need to configure instance.volumes.replacements to replace the old URI in Accumulo metadata.

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 </blockquote> -- https://github.com/mindscratch https://www.google.com/+CraigWickesser https://twitter.com/mind_scratch https://twitter.com/craig_links
