Snapshots timeouts

I am currently trying to create another hbase cluster by exporting snapshots from our main storage. While it worked well for the smaller tables, it failed on timeouts on larger tables while trying to CREATE the snapshots. I read a bit about it and found out that increasing

Re: Snapshots timeouts

There are actually three timeouts, and I only had success when increasing all three. Adding the following to hbase-site.xml should do the trick. property namehbase.snapshot.master.timeoutMillis/name value120/value /property property namehbase.snapshot.region.timeout/name value120/value

How to decide the next HMaster?

Could someone explain me which it's the process to select the next HMaster when the current one is gone down?? I've been looking for information about it in the documentation, but, I haven't found anything.

Hadoop Summit EU HBase Meetup Review

We had Hadoop Summit Europe last week where we had an HBase Meetup. First we had Enis talk about HBase Architectureand then Lars talked about some interesting HBase Use CasesFinally, we opened it up to the public where we had a frank discussion on the Uptake of HBase vs. other NoSQL DB's such

RE: Hadoop Summit EU HBase Meetup Review

Very interesting write up, but quite hard to read. configuration, installation, complexity, documentation ... these can be improved, no doubts, some other features (Inter DC replication and high availability) are still behind of Cassandra's I think and this should be prioritized by HBase

Efficiently scan table segments with coprocessor

Hi, We have a short and tall hbase table structure where a single user's data is stored across a set of rows in hbase. New events are inserted into a user's data, and the sorting of the rows handles the structure of the users data. Most of our user base is inactive at any given time. When a
