Offloading a volume to a tier by using the maprcli volume offload command fails with the following error:

ERROR (11) - Unable to start OFFLOAD for component-files, Gateway not assigned yet. Please retry after some time.

In addition, the maprcli volume tierjobstatus command shows the state of the offload operation as FailureFatal.

Workaround: Use these steps:

Identify the assigned gateway for the failing volume:

~$ maprcli volume tierjobstatus -name component-files -json -verbose true

Stop the gateway to force reassignment:

maprcli node services -name mastgateway -action stop -nodes $HOSTNAME

Restart the gateway using the following command:

 maprcli node services -name mastgateway -action restart -nodes <node> -json

MFS-15360

Copying a large number of objects to a bucket in the Object Store can result in an incorrect output list in the Object Store user interface (UI).

Workaround: Instead of referring to the UI, use the

/opt/mapr/bin/mc
                ls

command from the CLI to generate an accurate list of the objects. For more information, see mc ls.

MFS-15361

Incorrect object list output for the empty folder contents

MFS-15375

If you use the Object Store user interface (UI) to create a new bucket in a specific account, the bucket is not created in the specified account. Instead, the bucket is created in the default account.

Workaround: Use /opt/mapr/bin/mc commands to create the bucket. See Create Buckets. You can also use s3cmd or awscli to create buckets.

MFS-15672

In maprcli command for 'filter' option the operators other than "==" (Exact match) and "!=" ( Does not match ) are not working

Workaround: This issue has been fixed with a patch. To obtain the fix, apply the latest mapr-patch for your Data Fabric release version to your Data Fabric installation.

Upgrade Issues

OTSDB-147

After upgrading OpenTSDB from version 2.4.0 to version 2.4.1, the Crontab on each OpenTSDB node is not updated and continues to point to the previous OpenTSDB version.

Workaround: To fix the Crontab, run the following commands on each OpenTSDB node, replacing $MAPR_USER with the name of the cluster admin (typically mapr) :

RHEL

export CRONTAB="/var/spool/cron/$MAPR_USER"
sed -i 's/2.4.0/2.4.1/' $CRONTAB

SLES

export CRONTAB="/var/spool/cron/tabs/$MAPR_USER"
sed -i 's/2.4.0/2.4.1/' $CRONTAB

Ubuntu

export CRONTAB="/var/spool/cron/crontabs/$MAPR_USER"
sed -i 's/2.4.0/2.4.1/' $CRONTAB
