Hi, I'm new in big DATA,

I'm working with HDP 2.6.5, Ambari 2.6.2, HBase 1.1.2

I would like to make a weekly full backups of all tables of HBase (all regionservers and my HBase master)

and daily incremental backups of same things

No one has made a backup, so that's reason I am trying to make one.

HBase is kerberised. so I did a kinit as hbase user

I tried those commands on my hbase master (in local on it) :

hbase backup create full hdfs://[FQDN server]:[port]/ -set /etc/hbase/hbase_backup_full/test -w 3

goal : backup all tables in the file called test (I've created it so I don't understand why it tells me that's empty, and I've made a chown hbase:hbase on it as well as on the directory hbase_backup_full)
issue : 634 ERROR [main] util.AbstractHBaseTool: Error running command-line tool

IOException: Backup set '/etc/hbase/hbase_backup_full/test' is either empty or does not exist

could anyone help me please ?

Do I need to modify some config files to do this ? if yes which ?

Thanks 🙂

@kailash salton

I have tried as much as possible to explain the process of doing a successful hbase backup. I think for sure is to enable hbase backup by adding some parameters documented below.

There are a couple of things to do like copying the core-site.xml to the hbase/conf directory etc. I hope this process helps you achieve your target. I have not included the incremental that documentation you can easily find

Check the directories in hdfs

[hbase@nanyuki ~]$ hdfs dfs -ls /
Found 12 items
drwxrwxrwx   - yarn   hadoop          0 2018-12-17 13:07 /app-logs

drwxr-xr-x   - hdfs   hdfs            0 2018-12-17 13:04 /user

Created a backup directory in hdfs

[hdfs@nanyuki ~]$ hdfs dfs -mkdir /backup
[hdfs@nanyuki ~]$ hdfs dfs -chown hbase  /backup

Validate the backup directory was created with correct permissions

[hdfs@nanyuki ~]$ hdfs dfs -ls /
Found 13 items
drwxrwxrwx   - yarn   hadoop          0 2018-12-17 13:07 /app-logs

.......
drwxr-xr-x   - hdfs   hdfs            0 2018-12-17 13:04 /user

Invoked the hbase shell to check the tables

[hbase@nanyuki ~]$ hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 1.1.2.2.6.5.0-292, r897822d4dd5956ca186974c10382e9094683fa29, Fri May 11 08:00:59 UTC 2018
hbase(main):001:0> list_namespace
NAMESPACE
PDFTable
default
hbase
3 row(s) in 4.6610 seconds

Check the tables

hbase(main):002:0> list_namespace_tables 'hbase'
TABLE
acl
meta
namespace
3 row(s) in 0.1970 seconds

Hbase need a table called "backup" table in hbase namespace which was missing this table is created if hbase backup is enabled see below so I had to add the below parameters in Custom hbase-site at the same time enabling hbase backup

hbase.backup.enable=true
hbase.master.logcleaner.plugins=YOUR_PLUGINS,org.apache.hadoop.hbase.backup.master.BackupLogCleaner
hbase.procedure.master.classes=YOUR_CLASSES,org.apache.hadoop.hbase.backup.master.LogRollMasterProcedureManager
hbase.procedure.regionserver.classes=YOUR_CLASSES,org.apache.hadoop.hbase.backup.regionserver.LogRollRegionServerProcedureManager
hbase.coprocessor.region.classes=YOUR_CLASSES,org.apache.hadoop.hbase.backup.BackupObserver

After adding the above properties in Custom hbase-site and restarting hbase magically the backup table was created!

[hbase@nanyuki ~]$ hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell

Error with the backup command

[hbase@nanyuki ~]$ hbase backup create "full"  hdfs://nanyuki.kenya.ke:8020/backup  -set texas
2019-06-05 22:28:37,475 ERROR [main] util.AbstractHBaseTool: Error running command-line tool

To resolve the error "Backup set 'texas' is either empty or does not exist" I pre-emptively create the directory

[hdfs@nanyuki ~]$ hdfs dfs -touchz /backup/texas
[hdfs@nanyuki ~]$ hdfs dfs -ls /backup
Found 1 items
-rw-r--r--   3 hdfs hdfs          0 2019-06-05 22:51 /backup/texas

Check the core-site.xml is in /.../hbase/conf directory if not like below I copied the core-site.xml over

[root@nanyuki ~] cp /etc/hadoop/2.6.5.0-292/0/core-site.xml /etc/hbase/conf/

validate the copy

[root@nanyuki conf]# ls -lrt /etc/hbase/conf/
total 60
-rw-r--r-- 1 root  root   4537 May 11  2018 hbase-env.cmd
-rw-r--r-- 1 hbase hadoop  367 Sep 23  2018 hbase-policy.xml

............
-rw-r--r-- 1 root  root   3946 Jun  5 22:38 core-site.xml

Relaunched the hbase backup, it was like frozen but at last, I got a "SUCCESS"

[hbase@nanyuki ~]$ hbase backup create "full"  hdfs://nanyuki.kenya.ke:8020/backup
2019-06-05 22:52:57,024 INFO  [main] util.BackupClientUtil: Using existing backup root dir: hdfs://nanyuki.kenya.ke:8020/backup

Checked the YARN UI some backup process was going on see screenshot below hbase_backup.PNG

After successful backup see below screenshot hbase_backup2.PNG

Validate the backup was done this give some details like time, type "FULL" etc

[hbase@nanyuki hbase-client]$ bin/hbase backup show

@kailash salton

That is not the backup command I am interested in? Those commands are for listing and checking for the backup

$ hbase backup create "full"  hdfs://xxxxxxxxxxxxxxxxxxx

Show the command and the location of the backup directory
