--------------------------------
Summary: Better handling of NoSuchMethodException in
DfsLogger#open()
Key: ACCUMULO-2327
URL: https://issues.apache.org/jira/browse/ACCUMULO-2327
Project: Accumulo
Issue Type: Task
Reporter: Ted Yu
Currently NoSuchMethodException is ignored in the open method:
{code}
try {
// hsync: send data to datanodes and sync the data to disk
sync = logFile.getClass().getMethod("hsync");
e = null;
} catch (NoSuchMethodException ex) {}
{code}
Since logFile.getClass() would be the same for one log file, we can use boolean
field to indicate whether hsync is supported so that we don't call hsync again
and again if hsync is not supported.
A log statement for NoSuchMethodException would be desirable too.
