When HFiles are placed on a filesystem other than HDFS a rename operation can be a non-atomic file copy operation. It can take a long time to copy a large hfile and if interrupted there may be a partially copied file present at the destination. If we fail to “rename” the files into the archive we will continue to fail indefinitely. Before larger changes are considered, perhaps to StoreFileTracker, we should mitigate this problem.

README.md
Apache HBase is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al. Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Bigtable-like capabilities on top of Apache Hadoop.
Getting Start
To get started using HBase, the full documentation for this release can be found under the doc/ directory that accompanies this README. Using a browser, open the docs/index.html to view the project home page (or browse https://hbase.apache.org). The hbase 'book' has a 'quick start' section and is where you should being your exploration of the hbase project.
The latest HBase can be downloaded from the download page.
We use mailing lists to send notice and discuss. The mailing lists and archives are listed here
