> Page Blobs are primarily used by HBASE. HBASE replication, which apparently
> has not been used with WASB until recently, performs non-sequential reads on
> log files using PageBlobInputStream. There are bugs in this stream
> implementation which prevent skip and seek from working properly, and
> eventually the stream state becomes corrupt and unusable.
> I believe this bug affects all releases of WASB/HADOOP. It appears to be a
> day-0 bug in PageBlobInputStream. There were similar bugs opened in the past
> (HADOOP-15042) but the issue was not properly fixed, and no test coverage was
> added.
