HBase connection hangs
Hi,
whatever combination of lines below I use, the code always hangs on
connecting to HBase (last line). I am almost dead from attempts to make it
work.
Thank you very much.
Mark
hBaseConfig.addResource(new
Path("/etc/hbase/conf/hbase-site.xml"));
hBaseConfig.set("hbase.zookeeper.quorum", "mark-7");
hBaseConfig.set("hbase.zookeeper.property.clientPort",
"2181");
table = new HTable(hBaseConfig, "mytable");

Hi, Ted:
Our environment is using a distribution from a Vendor, so it is not easy just to patch it myself.
But I can seek the option to see if the vendor is willing to patch it in next release.
Before I do that, I just want to make sure patching the code is the ONLY solution.
I read the source code of Hive 0.9.0 of HiveHBaseTableInputFormat. I didn't see any place it invoked scan.setCaching(), so I don't think "set hbase.client.scanner.caching" in the hive session will work, but that is just my guess. There are quite a lot of messages on the internet that it will work in this case, so it confused me.
What I want to confirm is that "set hbase.client.scanner.caching" in fact doesn't work in hive for scan.setCaching(). Is that true?
Thanks
Yong

You can patch HIVE-3603 into your deployment so that you can make use of
scan.setCacheBlocks(false).

Hi Mark,
Base on this exception:
1. 1862 [pool-2-thread-1] WARN
org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper - Possibly
transient ZooKeeper, quorum=mark-7:2181,
exception=org.apache.zookeeper.KeeperException$ConnectionLossException:
KeeperErrorCode = ConnectionLoss for /hbase/hbaseid
look like you client is loosing connection with zookeeper. Check your code
for places where you closing connection to zookeeper. Also you may try to
restart zookeeper. Is your hbase woking properly ? What hbase hbck says ?
This exception:
014-01-13 23:11:47,803 [myid:] - WARN [NIOServerCxn.Factory:

EndOfStreamException: Unable to read additional data from client sessionid
0x1438f2725950005, likely client has closed socket
again indicate that something is going on when client is closing connection
to ZK server.
Cheers
Samir

Ted,

By the way, should I ask on a different mailing list?

Ted,
actually I get a better error than before, here,
http://pastebin.com/idE8R1hD
I am using the latest HBase installed with Cloudera.
By the way, should I ask on a different mailing list?
Thank you,
Mark

Putting common-user to bcc since this is an HBase related question.
Which version of HBase are you using ?
Can you say a bit more about the cluster you're connecting to ?
When your client hangs at the last line, can you get jstack and pastebin it
?
Thanks
