Subject [jira] Commented: (CASSANDRA-919) Add thrift request retries to Hadoop input format
Date Thu, 25 Mar 2010 17:47:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12849799#action_12849799
] 

Jonathan Ellis commented on CASSANDRA-919:
------------------------------------------

adding retries under retries doesn't seem like a good design to me.

let's focus on getting get_range_slice performance to the point where Hadoop only has to restart
map tasks at a rate we can live with.

> In order to decrease overhead of restarting a map task and increase reliability of the
record reader we should retry the get_range_slices requests if they fail.
