> Currently in HRegionFileSystem#splitStoreFile we are not creating reference
> files if the split row not lies in the storefile range that means one of the
> child region doesn't have any data.
> {code}
> // Check whether the split row lies in the range of the store file
> // If it is outside the range, return directly.
> if (top) {
> //check if larger than last key.
> KeyValue splitKey = KeyValueUtil.createFirstOnRow(splitRow);
> byte[] lastKey = f.createReader().getLastKey();
> // If lastKey is null means storefile is empty.
> if (lastKey == null) return null;
> if (f.getReader().getComparator().compareFlatKey(splitKey.getBuffer(),
> splitKey.getKeyOffset(), splitKey.getKeyLength(), lastKey, 0,
> lastKey.length) > 0) {
> return null;
> }
> } else {
> //check if smaller than first key
> KeyValue splitKey = KeyValueUtil.createLastOnRow(splitRow);
> byte[] firstKey = f.createReader().getFirstKey();
> // If firstKey is null means storefile is empty.
> if (firstKey == null) return null;
> if (f.getReader().getComparator().compareFlatKey(splitKey.getBuffer(),
> splitKey.getKeyOffset(), splitKey.getKeyLength(), firstKey, 0,
> firstKey.length) < 0) {
> return null;
> }
> }
> {code}
> In some cases when split row should be compared with part of rowkey(in
> composite rowkey) mainly for secondary index tables we need to create
> reference files even when split row not lies in the storefile range so that
> they can be rewritten to it's child regions by some custom half store file
> reader which compare the part of row key with split row.
> The check of comparing split row with storefile range and returning directly
> can be avoided by having special boolean attribute in table descriptor when
> it set to true. Or else we can have coprocessor hooks so that in the hooks we
> can create the references and bypass.
