Re: HBase is able to connect to ZooKeeper but the connection closes immediately

Hi All, Thank you for your reply. I tried all these options but still I am facing this issue. @Mayank: I tried the same, but still getting error. export HADOOP_CLASSPATH="/usr/lib/hadoop/:/usr/lib/hadoop/lib/:/usr/lib/hadoop/conf/" export HBASE_CLASSPATH="/usr/lib/hbase/:/usr/lib/hbase/lib/:/usr

Re: HBase is able to connect to ZooKeeper but the connection closes immediately

Actually zookeeper servers have an active connections limit, which by default is 30. You can increase this limit by setting maxClientCnxns property accordingly in your zookeeper config file, zoo.cfg. For example - maxClientCnxns=100but before that copy the hadoop-core-*.jar present inside hadoo

Re: HBase is able to connect to ZooKeeper but the connection closes immediately

Hi Tariq, Thank you!! I already changed the maxClientCnxns to 1000. Also we have set CLASSPATH that includes all the Hadoop,HBase & Zookeper path's. I think copying hadoop .jar files to Hbase lib folder is the same affect of setting CLASSPATH with all the folders. There is no commons-configuration

Dynamic load of Coprocessors

Hi all, I can't seem to understand if there is a way to dynamically load coprocessors ? The best way I found so far is using the shell: *alter 'URLS', METHOD => 'table_att', 'coprocessor'=>'|com.infolinks.hbase.coprocessors.HBaseTestRegionObserver||' * I leave the path empty because I put the j

You should see the explaination on the HBase´s book hbase.coprocessor.region.classes A comma-separated list of Coprocessors that are loaded by default on all tables. For any override coprocessor method, these classes will be called in order. After implementing your own Coprocessor, just put it

I apologize for hit send with an incomplete message. I will add that the ticket is HBASE-1936: ClassLoader that loads from HDFS. If I am not mistaken, this could be used to load coprocessors and filters without a grid or table bounce. Perhaps someone more in tune than me has more information. Ch

Re: Dynamic load of Coprocessors

When using the table attribute method you must specify a fully qualified Hadoop path URI to a jar, and it must be accessible to all regionservers i.e. on HDFS. (When opening a region of this table the regionserver will use the Hadoop Filesystem abstraction to copy the jar to a local temporary direc

About cells with duplicate timestamp information

I have read all I could find regarding what happens when you have multiple cells with the exact same address (r/f/q/t), and I'm still a little confused about the resolution. If I create 2 puts for the exact same address (r/f/q/t), the last one wins? Can I get different results from a scan as from

Re: Region is not online Execptions

Hi, You can have this if the region moved, i.e. was previously managed by this region server and is now managed by another. The client keeps a cache of the locations, so after a move it will first contact the wrong server. Then the client will update its cache. By default there are 10 internal ret

Hi, We had a similar issue. It our hbase-site.xml, we had given our hdfs path like this "hdfs://abc.xyz.com:9000\hbase". After checking in hdfs, we changed it to "hdfs://abc.xyz.com:9000:9000/user/hadoop/hbase" and then restarted HBase. It worked it. Please check your conf. On Fri, Jun 8, 2012
