Re: Region server not accept connections intermittently
I got the dump of the problematic rs from web ui: http://pastebin.com/4hfhkDUw output of top -H -p PID: http://pastebin.com/LtzkScYY I also got the output of jstack but I believe it's already in the dump so I do not paste it again. This time the hang lasted about 20 minutes. 于 2014/7/9 12:48, Esteban Gutierrez 写道: Hi Rural, Thats interesting. Since you are passing hbase.zookeeper.property.maxClientCnxns does it means that ZK is managed by HBase? If you experience the issue again, can you try to obtain a jstack (as the user that started the hbase process or try from the RS UI if responsive rs:port/dump) as Ted suggested? the output of top -H -p PID might be useful too where PID is the pid of the RS. If you have some metrics monitoring it would be interesting to see how callQueueLength and the blocked threads change over time. cheers, esteban. -- Cloudera, Inc.

Hey, +user@hbase Make sure you are placing 2.4 version hadoop jars in hbase/lib folder so that HBase picks correct jars during runtime.

how to measure IO on HBase

The second scenario will be slightly more complicated with the 'primary key' being stored in the memstore or HFile in parts. -- View this message in context: http://apache-hbase.679495.n3.nabble.com/how-to-measure-IO-on-HBase-tp4061207.html Sent from the HBase User mailing list archive at Nabble.com.

Need help on RowFilter
Hi Team,
Could you please help me to resolve below issue.
In my hbase table, i've a 30 records. I need to retrieve records based on
list of rowkeys. I'm using below code base. It is not giving records
HTable table = new HTable(configuration, tableName);
ListFilter filters = new ArrayListFilter();
Filter rowFilter=new RowFilter(CompareFilter.CompareOp.EQUAL, new
BinaryPrefixComparator(Bytes.toBytes(rowkey)));
filters.add(rowFilter);
Filter rowFilter=new RowFilter(CompareFilter.CompareOp.EQUAL, new
BinaryPrefixComparator(Bytes.toBytes(rowkey1)));
filters.add(rowFilter);
FilterList fl = new FilterList(filters);
Scan s = new Scan();
s.setFilter(fl);
ResultScanner ss = table.getScanner(s);
{
for(KeyValue kv : r.raw())
{
System.out.print(new String(kv.getRow()) + );
}
}
Thank you for support

Re: Need help on RowFilter
HI Rajesh,
If you know the rowkeys already, you don't need to perform a scan, you can just
perform a get on the list of rowkeys
e.g.
ListGet RowKeyList = new ArrayListGet();
# for each rowkey
RowKeyList.add(new Get(Bytes.toBytes(rowkey)));
Result[] results = table.get(RowKeyList);
for (Result r : results) {
for(KeyValue kv : r.raw()) {
System.out.print(new String(kv.getRow()) + );
}
}

Re: Need help on RowFilter
Hi Rajesh
From personal use, the rowFilter allows for finer grained results when
performing a large scan where the row keys don't exaclty match your criteria.
For example if you use start and end rows to constrain your scan, the results
may contain some results that you don't want and you can use the row Prefix
filter to only get the ones you want.
In the setup im using start and end rows are the fastest way to get to the
segments of data I need within hbase. The row filter is then used to
clean/restict the data, think of it like the HAVING clause in SQL if you are
used to that, It happens more in post processing of the result set.
Thats my understanding of how it should be used, others may have different
feedback on this.

Re: Need help on RowFilter
Hi Rajesh, It looks like the filter list combines filters with 'AND' operator. In your case you had two 'equal' rowfilters and expected each return a result. Mingtao Sent from iPhone On Jul 10, 2014, at 7:08 AM, Madabhattula Rajesh Kumar mrajaf...@gmail.com wrote: Rajesh
