Hi all, I'm running into an issue in HBase 1.1.2 where after a cluster is running for some time, disabling a table in the shell has no effect, hanging until the timeout limit is reached. Looking at the master logs there is only one message that has anything to do with it: 2016-02-12 13:16:23,237

Re: Rename tables or swap alias

Please see http://hbase.apache.org/book.html#ops.snapshots for background on snapshots. In Anil's description, table_old is the result of cloning the snapshot which is taken in step #1. See http://hbase.apache.org/book.html#ops.snapshots.clone Cheers On Tue, Feb 16, 2016 at 6:35 AM, Pat Ferrel

Re: Inserting different versions for a KeyValue through 2 HFiles while bulkloading

Hi Mehdi, HBase wil sort the KeyValues based on the timestamp. So if you keep just one version only the last one will be returned. If you keep more than one and ask them all of them, then you will get both, ordered by timestamp. HTH JMS 2016-02-16 5:19 GMT-05:00 Mehdi Ben Haj Abbes

Re: Rename tables or swap alias

I think I can work out the algorithm if I knew precisely what a “snapshot" does. From my reading it seems to be a lightweight fast alias (for lack of a better word) since it creates something that refers to the same physical data.So if I create a new table with cleaned data, call it table_new.

Inserting different versions for a KeyValue through 2 HFiles while bulkloading

Hi folks, I'm doing bulk loading. Let's imagine that I wrote a first version for a given KeyValue in HFile that I loaded in my table. Then for a further integration I will write another HFile that will contain a new version of the "same" KeyValue I wrote before. Will the second bulk load succeed.
