Solve HBase start error problem: No such file or directory!

Application Scenarios

After HBase was set up, Ben wanted to start hbase with a happy heart, test using hbase, but found that when you start HBase, report all kinds of errors, java_home,hbase,hadoop, etc. cannot find files or directories, no such file or Directory

# view hbase-env.sh file

 # cd/opt/hbase1.2.6/conf
 # vim hbase-env.sh

export hbase_manages_zk=false
Export Java_home= "/opt/jdk1.8"
export hadoop_home= "/opt/hadoop2.6.0"
export hbase_home= "/opt/hbase1.2.6
" Export hbase_classpath= "/opt/hadoop2.6.0/etc/hadoop"
export hbase_pid_dir= "/opt/hbase1.2.6/pids"

# Above this piece of configuration, all re-handwriting, do not copy from the Internet directly paste, which may have Chinese characters, resulting in the environment variable cannot be found

start hbase directly on the primary node after modification

# start-hbase.sh    

Note: You only need to start on the master node and the HBase service is automatically opened from the node
