Review request for Ambari, Jonathan Hurley and Vitalyi Brodetskyi.
Bugs: AMBARI-18492
https://issues.apache.org/jira/browse/AMBARI-18492
Repository: ambari
Description
-------
When running alerts in a large cluster (for example a cluster with 1300 hosts),
some alerts like the Stale Alert may create text too large to store in the
database.
On MySQL, for example, the size of a TEXT field is 65k (less if UTF-8 is used).
Normally, this is plenty of space. However, some clusters experience:
ERROR [alert-event-bus-1] AmbariJpaLocalTxnInterceptor:188 - [DETAILED ERROR]
Internal exception (1) :
com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column
'alert_text' at row 1
at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:4185)
Diffs (updated)
