----------------------------------------------
Summary: Ambari server backup error - failure if backup size
exceeds 4GB
Key: AMBARI-17593
URL: https://issues.apache.org/jira/browse/AMBARI-17593
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.4.0
Reporter: Nahappan Somasundaram
Assignee: Nahappan Somasundaram
Fix For: 2.5.0
*PROBLEM:*
When " ambari-server backup " is run it tries to zip the following directories:
{code}
/etc/
/var/lib/ambari-server/resources
/var/run/ambari-server/stack-recommendations/1/
{code}
And by any chance if the aggregated data in above directories exceeds 4gb you
get the following error:
{code}
A problem occurred while unzipping. Details: Zipfile size would require ZIP64
extensions
Could not create zip file. Details: Zipfile size would require ZIP64 extensions
{code}
*STEPS TO REPRODUCE :*
1)Exceed the Directory size greater than 4gb
2)Run ambari-server backup
*EXPECTED RESULT :* Backup should be successful and give something like:
{code:java}
[root@sandbox ~]# ambari-server backup
Using python /usr/bin/python
Backing up Ambari File System state... *this will not backup the server
database*
Backup requested.
No path specified. Will use /var/lib/ambari-server/Ambari_State_Backup.zip
Backup process initiated.
Creating zip file...
Zip file created at /var/lib/ambari-server/Ambari_State_Backup.zip
Backup complete.
Ambari Server 'backup' completed successfully.
{code}
*ACTUAL RESULT :* Backup fails with error:
{code:java}
[root@sandbox ~]# ambari-server backup
Using python /usr/bin/python
Backing up Ambari File System state... *this will not backup the server
database*
No path specified. Will use /var/lib/ambari-server/Ambari_State_Backup.zip
Backup requested.
Backup process initiated.
Creating zip file...
A problem occurred while unzipping. Details: Zipfile size would require ZIP64
extensions
Could not create zip file. Details: Zipfile size would require ZIP64 extensions
{code}
*SOLUTION/WORKAROUND:*
In the script :/usr/lib/python2.6/site-packages/ambari_server/BackupRestore.py
Comment out the line :
{code}
zipf = zipfile.ZipFile(self.zip_folder_path + self.zipname, 'w')
{code}
And add:
{code}
zipf = zipfile.ZipFile(self.zip_folder_path + self.zipname, 'w',allowZip64 =
True)
{code}
