--------------------------------------
Summary: Limit size of split rows
Key: ACCUMULO-3021
URL: https://issues.apache.org/jira/browse/ACCUMULO-3021
Project: Accumulo
Issue Type: Improvement
Affects Versions: 1.4.0
Reporter: Keith Turner
Fix For: 1.7.0
Just ran into an issue where a very large split row was added to Accumulo. The
large split row caused the metadata table to split and was pushed up into the
root tablet. This caused the root tablet to become unresponsive as many
clients and tservers tried to scan the root tablet. Had to write a custom
utility for 1.4 to fix this.
I am curious if 1.5 would have been able to merge it away. Even if 1.5 could
merge it away, the root tablet becoming unresponsive was really bad. It took a
lot of poking and proding to get the system to anything. It would be best to
avoid this situation altogether.
Could make the max split size configurable. This config would be used to limit
automatic and user added splits.
