New install; but originally I had setup HDFS without HA, then installed accumulo, then setup HA (not the smartest, but there you go). I noticed issues with accumulo pointing to the standby namenode, so I used the 'replacement' technique mentioned on this mailing list.
This is a CM managed Accumulo cluster; I'm installing with parcels (the only accumulo parcel was 1.6.0, which is why I started with it). (The old cluster is not managed with CM). I can't paste master and tablet server logs easily... :( Gist: - tabletservers (presumably the ones that have been assigned a tablet from the new table, which is all of them) throw the NPE exception .... "exception trying to assign tablet <tableid>;<split key>;<split key> hdfs://<nameservice>/accumulo/tables/<tableid>/...." ... "VolumeUtil.removeTrailingSlash(VolumeUtil.java:79)" - master reports that '<hostname> reports assignment failed for tablet <tableid>;<split key>;<split key> Anyways, putting a 1.6.2 parcel out seems to have done the trick: the tablets are being assigned now... (Maybe not the place to put it, but are you guys going to be putting out new accumulo parcels? Love CM btw, much better than what I was using before [rsync/puppet/ansible + zabbix]). Cheers!
