hbase远程调试

远程调试HBase
步骤：
1 修改HBASE_HOME/bin/hbase文件，增加-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=10444
如

figure out which class to run if [ “$COMMAND" = "shell" ] ; then elif [ "$COMMAND"="shell"];thenelif["COMMAND” = “master” ] ; then CLASS=‘org.apache.hadoop.hbase.master.HMaster’

HBASE_OPTS=“$HBASE_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=10444" elif [ "$HBASEO​PTS−Xdebug−Xrunjdwp:transport=dts​ocket,server=y,suspend=n,address=10444"elif["COMMAND” = “regionserver” ] ; then

CLASS=‘org.apache.hadoop.hbase.regionserver.HRegionServer’ elif [ “$COMMAND” = “rest” ] ; then CLASS=‘org.apache.hadoop.hbase.rest.Dispatcher’ elif [

“$COMMAND" = "thrift" ] ; then CLASS='org.apache.hadoop.hbase.thrift.ThriftServer' elif [ "$COMMAND"="thrift"];thenCLASS=′org.apache.hadoop.hbase.thrift.ThriftServer′elif["COMMAND” = “migrate” ] ; then

CLASS=‘org.apache.hadoop.hbase.util.Migrate’ elif [ “$COMMAND” = “zookeeper” ] ; then CLASS=‘org.apache.hadoop.hbase.zookeeper.HQuorumPeer’ else

CLASS=$COMMAND fi

2 修改HBASE_HOME/conf/hbase-site.xml文件
zookeeper.session.timeout 300000 ZooKeeper session timeout. This option is not used by HBase directly, it

is for the internals of ZooKeeper. HBase merely passes it in whenever a connection is established to ZooKeeper. It is used by ZooKeeper for hearbeats. In

milliseconds. hbase.zookeeper.property.tickTime 2000000 Property from

ZooKeeper’s config zoo.cfg. The number of milliseconds of each tick.
bin/start-hbase.xml，启动HBase集群。

3 设置eclipse

选择Remote Java Application，右键New
写入名字，选择要调试的工程
默认Connection Type(Socket Attach)
写入Host和port，点击Apply，Debug.

可以通过lsof -i 10444查看是否连接上。

4 加入断点，进行调试
在源码中createTable函数加断点
在远程hbase shell中写：create ‘t1’,‘f1’
即可进入断点处
