[jira] [Created] (HBASE-20877) Hbase-1.2.0 OldWals age getting filled and not purged by Hmaster

[Manjeet Singh (JIRA)]

Manjeet Singh created HBASE-20877:
-

 Summary: Hbase-1.2.0 OldWals age getting filled and not purged by 
Hmaster
 Key: HBASE-20877
 URL: https://issues.apache.org/jira/browse/HBASE-20877
 Project: HBase
  Issue Type: Bug
  Components: Replication
Affects Versions: 1.2.0
Reporter: Manjeet Singh


Hbase version 1.2.0 OldWals are getting filled and showing as below

7.2 K 21.5 K /hbase/.hbase-snapshot
0 0 /hbase/.tmp
0 0 /hbase/MasterProcWALs
18.3 G 60.2 G /hbase/WALs
28.7 G 86.1 G /hbase/archive
0 0 /hbase/corrupt
1.7 T 5.2 T /hbase/data
42 126 /hbase/hbase.id
7 21 /hbase/hbase.version
7.2 T 21.6 T /hbase/oldWALs

 

It;s not getting purged by Hmaster as oldWals are supposed to be cleaned in 
master background chore, HBASE-20352(for 1.x version) is created to speed up 
cleaning oldWals, in our case it's not happening.

hbase.master.logcleaner.ttl is 1 minutes

[jira] [Created] (HBASE-19071) Import from Hbase version 0.94.27 to higher version 1.2.1 not working

[Manjeet Singh (JIRA)]

Manjeet Singh created HBASE-19071:
-

 Summary: Import from Hbase version 0.94.27 to higher version 1.2.1 
not working 
 Key: HBASE-19071
 URL: https://issues.apache.org/jira/browse/HBASE-19071
 Project: HBase
  Issue Type: Bug
  Components: hbase
Affects Versions: 1.2.1
Reporter: Manjeet Singh


Data migration from one cluster to another cluster in same N/W, but with a 
different version of hbase one is 0.94.27 (source cluster hbase) and another is 
destination cluster hbase version is 1.2.1. is not working.

I have used below command to take backup of hbase table on source cluster is:
 ./hbase org.apache.hadoop.hbase.mapreduce.Export SPDBRebuild /data/backupData/
and as a result below files were genrated by using above command:-
drwxr-xr-x 3 root root4096 Dec  9  2016 _logs
-rw-r--r-- 1 root root   788227695 Dec 16  2016 part-m-0

-rw-r--r-- 1 root root 14217981341 Dec 16  2016 part-m-6
-rw-r--r-- 1 root root   0 Dec 16  2016 _SUCCESS
 I import these file in another Hbase version (1.2.1)

in order to restore these files I am assuming I have to move these files in 
destination cluster and have to run below command 

hbase org.apache.hadoop.hbase.mapreduce.Import   


sudo -u hdfs hbase org.apache.hadoop.hbase.mapreduce.Import test_table  
hdfs://:8020/data/ExportedFiles

I am getting below error

"com.miguno.avro", "fields" : [ { "name" : "username", "type" : "string",
"doc" : "Name of the user account on Twitter.com" }, { "name" : "tweet",
"type" : "string", "doc" : "The content of the user's Twitter message" } ] }
