See if Hadoop is working and the process is complete

View disk usage

From here we can see that the space of the trader is empty.

The reason may be that there was a problem with Hadoop formatting

Then the files in the logs and TMP are all deleted, reformatted and unsuccessful, and later see the Clusterid inconsistency problem

Modified the Clusterid in the version file with the in-inconsistent state problem,

Increased the number of hadoop-hdfs.xml in the

<property> <name>dfs.name.dir</name> <value>/soft/hadoop/name</value> # Hadoop's name directory path     </property> <property> <name>dfs.data.dir</name> <value>/soft/ Hadoop/data</value> #hadoop的data目录路径 </property>

Reformat and then start it.

It was a whole morning of rolling and tossing 、、、
