'jps does not show hmaster but <no information available>
I configured HBase today and I configured it correctly at first. However, when I ran HBase use the code 'start-all.sh' again, I could not see 'Hmaster' anywhere. It just shows like:
[root@master bin]# jps
25164 QuorumPeerMain
83447 HRegionServer
44542 NameNode
44789 DataNode
45098 SecondaryNameNode
45378 ResourceManager
45536 NodeManager
56678 <no information available>
56949 Jps
when I 'jps' again, '': enter image description here and the log shows:
[root@master bin]# cd /home/hadoop/hbase-2.2.3/logs
[root@master logs]# ls

Solution 1:[1]
I solve the problem by adding the following configuration to the configuration file "hbase-site.xml":
<property>
<name>hbase.unsafe.stream.capability.enforce</name>
<value>false</value>
</property>
I do not why, but it works.
