haduzilla's Issues

manual

should we have a manual for basic introduce about what is this project and some tips like the default password for user.

service not work on hadoop cdh3

the error message like
2013-11-21 12:10:37,490 ERROR org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:mapred (auth:SIMPLE) cause:org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot set permission for /var/lib/hadoop-0.20/cache/mapred/mapred/system. Name node is in safe mode.
The number of live datanodes 0 needs an additional 1 live datanodes to reach the minimum number 1. Safe mode will be turned off automatically.
2013-11-21 12:10:37,492 INFO org.apache.hadoop.ipc.Server: IPC Server handler 6 on 8020, call setPermission(/var/lib/hadoop-0.20/cache/mapred/mapred/system, rwx------) from 10.0.0.254:44369: error: org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot set permission for /var/lib/hadoop-0.20/cache/mapred/mapred/system. Name node is in safe mode.

after manual create folder and set permission to 700, the name node work fine.

disable drbl mkswap

drbl will generate 128M swap file to data node partition but it's not necessary because we have swap partition. For better performance, should we close auto mkswap file?

genisoimage syntex need to change to support EFI

ubuntu 12.04.3 and 13.10 ISO file are partitioned by EFI partition.
But bigtop-0.7.0 and CentOS-6.5 ISO are partitioned by hidden HPFS/NTFS.

genisoimage need to add --efi-boot option in future to support uEFI BIOS.

Upgrade, Re-install after daily operation

If user had installed DRBL and Hadoop related software stack, run for a period, they now have historical data in HDFS, historical job history in server, how can they re-install or upgrade the software stack ?

  1. Could it be possible to have a script to upgrade or re-install related packages ?
  2. If user failed to change the setting, what should they do ?
