[jira] [Comment Edited] (HBASE-27275) graceful_stop.sh unable to restore the balance state
[ https://issues.apache.org/jira/browse/HBASE-27275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17575895#comment-17575895 ]

-------------------------------------------------------------
[~zhangduo] sir:
head -1 is: "hbase:001:0> balance_switch false"
tail -1 is : "hbase:002:0>"
In the above example, #line 3 and #line 5 of 'true' represent the previous balance status, so we can use the value of {color:#172b4d}#line 5{color} as the state of the previous balance.

> Key: HBASE-27275
> URL: https://issues.apache.org/jira/browse/HBASE-27275
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 2.5.0, 3.0.0-alpha-4
> Reporter: LiangJun He
> Assignee: LiangJun He
> Priority: Blocker
>
> When executing the command ’graceful_stop.sh --restart --reload‘, the balance state cannot be restored normally. Because the related command returned the wrong result:
> {code:java}
> HBASE_BALANCER_STATE=$(echo 'balance_switch false' | hbase shell -n | tail -1)
> echo ${HBASE_BALANCER_STATE}
> hbase:002:0>
> {code}
>
> The information returned by "echo 'balance_switch false' | hbase shell -n" is as follows:
> hbase:001:0> balance_switch false {color:#ff0000}#line 1{color}
> 2022-08-05 22:41:57,269 INFO [RPCClient-NioEventLoopGroup-1-1] Configuration.deprecation: hbase.client.pause.cqtbe is deprecated. Instead, use hbase.client.pause.server.overloaded {color:#ff0000}#line 2{color}
> Previous balancer state : true {color:#ff0000}# line 3{color}
> Took 0.6787 seconds {color:#ff0000}#line 4{color}
> => true {color:#ff0000}#line 5{color}
> hbase:002:0> {color:#ff0000}#line 6{color}
>
> head -1 is {color:#172b4d}#line 1{color}: "hbase:001:0> balance_switch false"
> tail -1 is {color:#172b4d}#line 6{color}: "hbase:002:0>"
>
> {color:#172b4d}balance_switch.rb is as follows:{color}
> {code:java}
> def command(enableDisable)
> prev_state = !!admin.balance_switch(enableDisable)
> formatter.row(["Previous balancer state : #{prev_state}"])
> prev_state
> end{code}
> #line 3 and #line 5 of 'true' represent the previous balance status.
> So we can use the value of {color:#172b4d}#line 5{color} as the state of the previous balance.
