Hbase Error java.lang.RuntimeException: Unable to run quorum server

Question

我不能启动Hbase，每当我启动时，我只得到Hmaster和Hregionserver的jps。Hquorompeer不断丢失。我检查了日志，我得到以下错误：

java.lang.RuntimeException: Unable to run quorum server

Answer 1

您遇到此错误的原因可能是Zookeeper存储快照和日志的数据目录已损坏。

为了避免zookeeper守护进程消亡，您需要提供一个新目录的路径，HQuorumpeer可以在该目录中存储其快照。为此，您需要在Hbase.site.xml中添加以下属性

<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>location of the newly created folder</value>
<description>Property from ZooKeeper's config zoo.cfg.
The directory where the snapshot is stored.
</description>
</property>

Answer 2

“zookeeper”的默认路径是/tmp/hbase-*/zookeeper(/tmp/hbase-hadoop/zookeeper)，删除它，然后再次尝试启动hbase.zookeeper.property.dataDir

Answer 3

从ZooKeeper目录中删除所有文件解决了此问题。在我的情况下

rm /var/lib/zookeeper/version-2/*
