Ted Yu commented on HBASE-4161:
-------------------------------
Thanks for the update.
Looking at processDeleteOnExit in FileSystem.java:
{code}
catch (IOException e) {
LOG.info("Ignoring failure to deleteOnExit for path " + path);
}
{code}
exists() throws IOException.
I wonder what other IOException may come out of exists(). Should we catch such
exception ?

> While opening a region, the HBase regionserver tries to list all the children
> in a "recovered.edits" directory. This directory may not exist and depending
> on the version of HDFS listStatus() might return null or an exception. If it
> does throw an exception the entire process of opening the region is aborted,
> just because the recovered.edits directory is not present.
