Jonathan Gray commented on HBASE-3417:
--------------------------------------
In StoreFile.java:
{code}
private static final Pattern REF_NAME_PARSER =
- Pattern.compile("^(\\d+)(?:\\.(.+))?$");
+ Pattern.compile("^([0-9a-f]+)(?:\\.(.+))?$");
{code}
If you ever need to go backwards from 92 to a previous version.
> CacheOnWrite is using the temporary output path for block names, need to use
> a more consistent block naming scheme

> Currently the block names used in the block cache are built using the
> filesystem path. However, for cache on write, the path is a temporary output
> file.
> The original COW patch actually made some modifications to block naming stuff
> to make it more consistent but did not do enough. Should add a separate
> method somewhere for generating block names using some more easily mocked
> scheme (rather than just raw path as we generate a random unique file name
> twice, once for tmp and then again when moved into place).
