VOLUME_ALARM_TABLE_LARGE_ROW_WARNING

Meaning

A row in a table within the specified volume has reached 75% of the maximum supported row size of 2 GB. The alarm provides the rowkey and the name of the table. If the rowsize exceeds 2 GB, subsequent MapR-DB operations on the corresponding table region will fail with an I/O error.

Resolution

Ensure that client applications that access the table are managing row data correctly, so that no row exceeds 2 GB. The method of resolving the alarm depends on the way in which client applications were managing row data.

For example, if client applications allowed too many versions of cell data, delete excess versions. If client applications neglected to remove old columns or column families, remove those manually.
