> Components: hbase
> Affects Versions: 1.1.12

> Priority: Critical
> Attachments: HBASE_18743.patch, HBASE_18743_v1.patch,

> We recently had a critical production issue in which HFiles that were still
> in use by a table were deleted.
> This appears to have been caused by conditions in which table have the same
> namespace and name with a default table cloned from snapshot.when snapshot
> and default table be deleted,HFiles that are still in use may be deleted.
> For example:
> Table with default namespace is: "t1"
> The namespace of the new table is the same as the name of the default table,
> and is generated by snapshot cloned : "t1: t1"
> When the snapshot and the default namespace table are deleted, the new table
> is also deleted in the used HFiles
> This is because the creation of the BackReferenceFile get the table Name is
> not normal, resulting in can not find the reference file, hfilecleaner to
> delete the HFiles in used, when the table has not been major compact
> {code:java}
> public static boolean create(final Configuration conf, final FileSystem fs,
> final Path dstFamilyPath, final TableName linkedTable, final String
> linkedRegion,
> final String hfileName, final boolean createBackRef) throws IOException
> {
> String familyName = dstFamilyPath.getName();
> String regionName = dstFamilyPath.getParent().getName();
> String tableName =
> FSUtils.getTableName(dstFamilyPath.getParent().getParent())
> .getNameAsString();
> {code}
> {code:java}
> public static TableName getTableName(Path tablePath) {
> return TableName.valueOf(tablePath.getParent().getName(),
> tablePath.getName());
> }
> {code}
