Re: HBase acl commands are too slow

Hi, I don't think the problem from zookeeper quorum. Create, scan and list commands are working without delay. It won't take more than 5 seconds. But when executing acl commands getting slow response. I have noticed in log as *auth: SIMPLE *but actually it should be *KERBEROS *authentication.

Re: Scan.setMaxResultSize and Result.isPartial

You should probably read https://blogs.apache.org/hbase/entry/scan_improvements_in_hbase_1 first. In HBase-1.1 and later code bases, you can call Scan.allowPartialResults() to instruct the ClientScanner to give you partial results. In this case, you can use Result.isPartial() to stitch together

Scan.setMaxResultSize and Result.isPartial

Hello, We are running 1.2.0-cdh5.7.0 on our server side, and 1.0.0-cdh5.4.5 on the client side. We're in the process of upgrading the client, but aren't there yet. I'm trying to figure out the relationship of Result.isPartial and the user, when setMaxResultSize is used. I've done a little

Re: what causes "Memst oreFlusherChore requesting flush" messages?

so what you're saying is that everyone will see at least 1 of those lines roughly every hour no matter what, and under higher load you'll see it when ever limits are hit for either WAL or Memstore causing flushes. So by the sounds of it, it's perfectly normal to be seeing a slew of those in the

Re: what causes "Memst oreFlusherChore requesting flush" messages?

This is done to prevent runaway WAL files. WAL file can't be deleted if some unflushed edits from this file exist in RS memstore. In case of a high load this may lead to accumulation of a large number of WAL files in a file system. -Vlad On Fri, Jun 17, 2016 at 12:49 PM, Vladimir Rodionov

Re: what causes "Memst oreFlusherChore requesting flush" messages?

>> has an old edit Yes, this is what PeriodicMemstoreFlusher does: it checks if there are edits older than (1h, but configurable) in memstore and flushes this memstore if find old edits. -Vlad On Fri, Jun 17, 2016 at 11:49 AM, Ted wrote: > Wondering if anyone knows the

Re: HBase acl commands are too slow

I have gone through the log but haven't identified the cause. Can you outline the time range for the 30 second response so that I can correlate with the log ? Is communication with zookeeper quorum working without noticeable delay ? Thanks On Fri, Jun 17, 2016 at 3:47 AM, kumar r
