Re: Accumulo Tip: Batch your Mutations

Also the native map is a Map> ... when doing updates for a mutation, it gets the Map once and uses that.This can be much faster than a Map, because for Map each insert may have to traverse a deeper tree than inserting into Map

Re: BatchScanner behavior with AccumuloRowInputFormat

The benefit of using a BatchScanner in the AccumuloRowInputFormat is that it can fetch multiple ranges in parallel within each Mapper. This may be able to help you manage your MapReduce job resources a bit better (see the discussion in the JIRA issue for details). If you don't need to use it, I

openjdk, Accumulo master state doesn't change from HAVE_LOCK to NORMAL

Accumulo 1.7.0 with HDFS 2.7.1 I was experimenting with openjdk instead of Oracle JRE for Accumulo and ran into this issue. It seems like because it never transitions from HAVE_LOCK to NORMAL, it never gets around to start the thrift server. Changing back to Oracle JRE didn't make a

RE: openjdk, Accumulo master state doesn't change from HAVE_LOCK to NORMAL

Thank you! What might be going on with the state transition of the master? Looks like the tservers can’t talk to the master without the thrift interface. Is there another interface I can enable on the master? From: Christopher [mailto:ctubb...@apache.org] Sent: Thursday, December

Re: openjdk, Accumulo master state doesn't change from HAVE_LOCK to NORMAL

This issue described doesn't seem related to the JDK. Yes, you should expect Accumulo to work with OpenJDK. While we don't prescribe a JDK for users, most of the developers have an interest in ensuring at least OpenJDK and Oracle JDK work well. A few people care about IBM JDK also, and we accept

Re: openjdk, Accumulo master state doesn't change from HAVE_LOCK to NORMAL

I can't be sure why the master is stuck in that state. It could be a bug in 1.7.0. Can you reproduce in 1.7.2? On Thu, Dec 1, 2016 at 5:56 PM Jayesh Patel wrote: > Thank you! > > > > What might be going on with the state transition of the master? Looks > like the tservers
