Subject [jira] [Commented] (CASSANDRA-2116) Separate out filesystem errors from generic IOErrors
Date Sun, 22 Jul 2012 01:20:35 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13420039#comment-13420039

Jonathan Ellis commented on CASSANDRA-2116:
-------------------------------------------

bq. I don't want to make people choose between wrapping the real exception in IOE or RTE or
swallowing everything.

The status quo is "IOE or RTE."  IOE is superseded by FSWE, and RTE can stay the same.  If
we need to improve things beyond that, it's out of scope for this ticket.

bq. Actually it can't throw 

You're right.

> We throw IOErrors everywhere today in the codebase. We should separate out specific errors
such as (reading, writing) from filesystem into FSReadError and FSWriteError. This makes it
possible in the next ticket to allow certain failure modes (kill the server if reads or writes
fail to disk).
