java - hbase Regionserver 启动，zookeeper 启动但 hmaster 未启动(regionserver.HRegionServer : Failed construction RegionServer)

Question

Hbase zookeeper 启动，regionserver 在多节点集群上启动，但 hmaster 未启动并生成以下日志文​​件。

hbase-site.xml 快照

两台机器datanode和namenode:

在datanode上:jps命令显示

10977 HRegionServer
10810 HQuorumPeer
1675 DataNode

在名称节点上:jps 命令显示

12017 ResourceManager
2353 NameNode
14904 Jps
11326 Jps

我在过去 4 天尝试连接它，安装了很多次 hbase。请帮助我，所有设置都在 Ubuntu 16 上。

以下是区域服务器日志文件:

Answer 1

在我的安装中我有:

• Ubuntu 18.04
• Hadoop 3.1.1
• HBase 2.1.0

在 this question 中讨论了同样的错误。

在启动 HBase Master Daemon 时我遇到了同样的错误:

2018-10-17 17:53:17,058 ERROR [main] regionserver.HRegionServer: Failed construction RegionServer java.lang.NoClassDefFoundError: org/apache/htrace/SamplerBuilder
        at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:635)  at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:619) ...

我猜这个错误的发生是因为 HBase master 使用来自 HADOOP_HOME 的 jar 并且在那里找不到 htrace-core 库。

我检查了哪些 htrace jar 位于 HBASE_HOME 和 HADOOP_HOME 中:

$ find $HBASE_HOME/ -type f -name 'htrace-core*' -ls
   689258   1472 -rw-r--r--   1 hadoop   hadoop    1506370 июл  6 18:28 /opt/hbase-2.1.0/lib/client-facing-thirdparty/htrace-core4-4.2.0-incubating.jar
   689260   1444 -rw-r--r--   1 hadoop   hadoop    1475955 июл  6 18:33 /opt/hbase-2.1.0/lib/client-facing-thirdparty/htrace-core-3.1.0-incubating.jar

$ find $HADOOP_HOME/ -type f -name 'htrace-core*' -ls
   672815   1444 -rw-r--r--   1 hadoop   hadoop    1475955 авг  2 09:50 /opt/hadoop-3.1.1/share/hadoop/yarn/timelineservice/lib/htrace-core-3.1.0-incubating.jar
   673317   1468 -rw-r--r--   1 hadoop   hadoop    1502280 авг  2 09:28 /opt/hadoop-3.1.1/share/hadoop/common/lib/htrace-core4-4.1.0-incubating.jar
   656456   1444 -rw-r--r--   1 hadoop   hadoop    1475955 июл  6 18:33 31 /opt/hadoop-3.1.1/share/hadoop/hdfs/lib/htrace-core4-4.1.0-incubating.jar

因此，我将 htrace-core-3.1.0-incubating.jar 从 HBASE_HOME 放入 $HADDOP_HOME/share/hadoop/common/lib。

我遇到了下一个错误:

2018-10-17 18:13:18,380 ERROR [Thread-14] master.HMaster: Failed to become active master

正如 here 所说，我们需要的只是简单地自己重新编译 HBase 或将属性放入 hbase-site.xml:

<property>
  <name>hbase.unsafe.stream.capability.enforce</name>
  <value>false</value>
</property>

我采取了第二种方式。然后 Hbase 就启动了。
