我正在尝试以独立模式在 HBase 上使用 OpenTSDB。下面是我的 hbase-site.xml。
<property>
<name>hbase.rootdir</name>
<value>file:///home/root/HBASE/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/root/HBASE/zookeeper</value>
</property>
我正在通过以下命令启动 hbase
./bin/start-hbase.sh
当我尝试启动 OpenTSDB 时，我在opentsdb.log中收到以下错误日志
java.net.ConnectException: Connection refused
at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) ~[na:1.7.0_85]
at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:744) ~ [na:1.7.0_85]
at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1143) ~ [zookeeper-3.3.6.jar:3.3.6-1366786]
02:55:53.767 INFO [ClientCnxn.startConnect] - Opening socket connection to server localhost/127.0.0.1:2181
02:55:53.769 WARN [ClientCnxn.run] - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
什么时候在启动 OpenTSDB 后立即尝试jps我得到以下输出
[root@Flume_Server hbase-0.94.8]# jps
12321 TSDMain
12359 Jps
12085 HMaster
759 Main
但经过一段时间后，我的输出低于jps
[root@Flume_Server conf]# jps
12476 Jps
12439 TSDMain
759 Main
以下是我在 hbase 日志中遇到的错误
