Hi All,
I have set up the Hbase in standalone mode. Both my server an client are
running on the same box.
When I tried to load a large amount of data, the client is hanging after
loading around 320000 records.
It looks, it may be a timeout issue. Please find below the snippet from
logs,
2010-07-07 11:32:25,993 INFO org.apache.zookeeper.server.NIOServerCnxn:

Also, I have made changes to hbase-default.xml as below,
<property>
<name>hbase.zookeeper.property.tickTime</name>
<value>20000</value>
<description>Property from ZooKeeper's config zoo.cfg.
The number of milliseconds of each tick. See
zookeeper.session.timeout description.
</description>
</property>
<property>
<name>hbase.zookeeper.property.initLimit</name>
<value>20</value>
<description>Property from ZooKeeper's config zoo.cfg.
The number of ticks that the initial synchronization phase can take.
</description>
</property>
<property>
<name>hbase.zookeeper.property.syncLimit</name>
<value>20</value>
<description>Property from ZooKeeper's config zoo.cfg.
The number of ticks that can pass between sending a request and
getting an
acknowledgment.
</description>
</property>
<property>
<name>zookeeper.session.timeout</name>
<value>400000</value>
<description>ZooKeeper session timeout.
HBase passes this to the zk quorum as suggested maximum time for a
session. See
http://hadoop.apache.org/zookeeper/docs/current/zookeeperProgrammers.html#ch_zkSessions
"The client sends a requested timeout, the server responds with the
timeout that it can give the client. The current implementation
requires that the timeout be a minimum of 2 times the tickTime
(as set in the server configuration) and a maximum of 20 times
the tickTime." Set the zk ticktime with
hbase.zookeeper.property.tickTime.
In milliseconds.
</description>
</property>
<property>
<name>hbase.regionserver.lease.period</name>
<value>400000</value>
<description>HRegion server lease period in milliseconds. Default is
60 seconds. Clients must report in within this period else they are
considered dead.</description>
</property>
But still, I am getting the same error, the client hangs.
Please let me know, if I am doing anything wrong or are there some other
settings which I need to make.
Thanks,
Manu
