Re: LoadIncrementHFiles.doBulkLoad() generates permissions exception

Jon. Were you running cdh3 with security turned on? LoadIncrementHFiles.doBulkLoad() seems to split a HFile to pieces at the same folder then load them. In your case, the mr job created the HFile under geoff directory where hbase user doesn't have write permission. You can try to put the

Re: Socket Timeout Exception when executing coprocessor

Nichole. Himanshu is right. Your coprocessor at some regions took too long to complete which caused the timeout. Can you do some profiling at the problematic region? Just adding some log message in the coprocessor might be okay. If all coprocessors (one per region) at a RS are performing a

Errors after major compaction

Hi, I have a cluster of 5 nodes with one large table that currently has around 12000 regions. Everything was working fine for relatively long time, until now. Yesterday I significantly reduced the TTL on the table and initiated major compaction. This should have reduced the table size to about 20%

Hi, I am doing bulk insertion into Hbase using Map reduce reading from lot of small(10MB approximation) files, resulting mappers = no of files. I am also monitoring the performance using Ganglia. The machines are c1.xlarge for processing the files(task trackers+data nodes) and m1.xlarge for

Re: Add a column family to a table

We add an argument here on that issue: Can somebody put a little bit light on the reason we need to disable the table in order to add CF? It looks to me that adding CF should be simple as say: there is a new one - anyway its on different file? What do I miss here? Thanks! Ophir On Sat, Jun 18,

Re: Add a column family to a table

Re: http://hbase.apache.org/book.html#regions.arch The high-level hand-waving answer is that it's not just one file. Since clients talk directly to RegionServers, all the regions need to be in sync in terms of table/region/CF metadata. On 6/30/11 11:44 AM, Ophir Cohen oph...@gmail.com

Table coprocessor loaded twice when region is initialized?

Hi, I'm debugging a prePut hook which I've implemented as part of the coprocessor work being developed. This hook is loaded via a table COPROCESSOR attribute and I've noticed that the prePut method is being called twice for a single Put. After setting up the region server to run in a debugger,

how to get hbase 0.92.0 or any other version could work with hadoop 0.21.0

Hi, I am working on a research project which used Hadoop 0.21.0, and I want to add HBase on top of that. But it seems there is no a released version of HBase could work with Hadoop 0.21.x. I saw 0.92.0 will support hadoop 0.21.x. But I when I tried to check out the version from SVN, I cannot

Re: how to get hbase 0.92.0 or any other version could work with hadoop 0.21.0

HBase trunk will be 0.92.0 when released. HBASE-2233 (Support both Hadoop 0.20 and 0.22) went into trunk on June 9th. I have not personally tried it, though. Best regards,    - Andy Problems worthy of attack prove their worth by hitting back. - Piet Hein (via Tom White) - Original
