Hello,
I am getting this YADE all the time
HBASE_HEAPSIZE=8000
Settings: -ea -XX:+UseConcMarkSweepGC -XX:MaxGCPauseMillis=200
-XX:+HeapDumpOnOutOfMemoryError -XX:+CMSIncrementalMode -XX:+UseParNewGC
-XX:CMSInitiatingOccupancyFraction=50 -XX:+UseCMSInitiatingOccupancyOnly
-XX:NewSize=256m -XX:Ma
Also,
why is the CMS not kicking in early, i have set XX:+
UseCMSInitiatingOccupancyOnly???

hi every one,
i am quite new to base and java. I have a few questions.
1. on the web ui for hbase i have the following entry in the region server
mining,60020,13711358624Fri Jun 14 00:04:22 GMT 2013requestsPerSecond=0,
numberOfOnlineRegions=106, usedHeapMB=5577, maxHeapMB=7933
when the hbase is
thank you very much.
i will try with snappy compression with data_block_encoding

Thanks,
is there any specific compression that is recommended of the use case i
have?
Since my values are all null will compression help?
I am thinking of using prefix data_block_encoding..

I want to have faster reads.
Please suggest.

hi everyone,
when i launch my mapreduce jobs to increment counters in hbase i
sometimes have maps
with multiple attempts like:
attempt_201303251722_0161_m_74_0
attempt_201303251722_0161_m_74_1
if there are multiple attempts running and if the first one gets
completed successful,
different docs and do the increments.
Sincerely,
Prakash Kadel

I am a newbee to HBASE. I am not sure this is the way
its a local read. i just check the last param of PostCheckAndPut indicating if
the Put succeeded. Incase if the put success, i insert a row in another table

one more question.
even if the coprocessors are making insertions to different region, since i use
"postCheckAndPut" shouldnt there be not much prefomance slow down?
thanks

coprocessor was to make the insertion code cleaner
and efficient index creation.

thank you lars,
That is my guess too. I am confused, isnt that something that cannot be
controlled. Is this approach of creating some kind of index wrong?

hi,
i am trying to insert few million documents to hbase with mapreduce. To
enable quick search of docs i want to have some indexes, so i tried to use the
coprocessors, but they are slowing down my inserts. Arent the coprocessors not
supposed to increase the latency?
my settings:
3 regio
20 matches
