-------------------------------------
Summary: scan page in monitor is causing the monitor to crash w/OOM
Key: ACCUMULO-3407
URL: https://issues.apache.org/jira/browse/ACCUMULO-3407
Project: Accumulo
Issue Type: Bug
Components: monitor
Affects Versions: 1.6.1
Environment: very large production cluster
Reporter: Eric Newton
Assignee: Eric Newton
Fix For: 1.6.2, 1.7.0
The monitor is now collecting information about scans. This will include any
scan-time arguments passed to the scan, but this information is not displayed.
It continues to use up memory, and when there are several thousand scans, and
each has a megabyte of arguments, it can cause a reasonably sized monitor to
OOM. Should also double-check that the monitor is cleaning up references with
each refresh.
It was unexpected that users would pass a megabyte of options to their queries.
