Hi,
Can you please help to see if there is any feature in HBase which will
satisfy following?
1) I need something which will be native to HBase and
2) Which will be able to execute some code at certain interval like daily
or weekly.
Is there any HBase feature which satisfies these two
CPs are core extensions which act as pre/post hooks for events happening in
the system. (like put, flush, compaction etc). This is not like cron jobs
which can be scheduled. What action you want to run as cron job? Depending
on that we can say whether HBase already allow some
But you can still do call end points with a cronjob from a gateway node
maybe? like echo blablabla | hbase shell from a script run daily?

Just have to say that hbase.master.loadbalance.bytable saved us after we
discovered it. In our case we had to set it manually to true, and then it
was easy to catch hot spotting on unusually large regions and handle it.
Btw +1 for HBASE-13013, had to say it, something that makes me starting
Yep, I think I figured the same. But I think it does'nt start it at the end
even if it tries, right?

Hi
My Hbase version is 1.0 running on mac, it seems a bug .
Hi,
So it was the case that the region sizes were very skewed, partly due to
the IncreasingToUpperBoundRegionSplitPolicy, which favours making lots of
smaller regions early on.
I couldn't find a tool to show regions and their sizes, for a specific
table, so ended up writing one.
I used that

Nasron,
Would you mind having a look at the patch/RB on HBASE-13103? Does the API
pair RegionNormalizer/Normalization
Hi Mikhail,
Something like N * number of region servers, or something different?
It's pretty much this, but additionally also trying to ensure that in best
case we can fit the whole column in memory per region server.
Another restriction is that since # MR map tasks == # of regions, keeping
Nasron,
Yeah, looks like you pretty much implemented pieces of logic being
discussed in HBASE-13103 :) So that's interesting, thanks for telling
us. Wondering, how did you estimate the number of desired regions?
