> wrong logic in HRegion.bulkLoadHFiles(List)
> -------------------------------------------
>
> Key: HBASE-8192
> URL: https://issues.apache.org/jira/browse/HBASE-8192
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.94.1, 0.94.2, 0.94.3, 0.94.4, 0.94.5
> Reporter: Chenghao Jiang
> Labels: patch
> Fix For: 0.94.7

> the wrong logic is here:
> when a ColumnFamily does not exist, it gets a null store object, then
> ioes.add(ioe); failures.add(p)
> but the code below, if (failures.size() != 0), it prints a warn log and
> return false, so it will never go into the code if (ioes.size() != 0) below,
> and IOException will not be thrown, then the client will keep retry forever.
> there is the same situation when doing store.assertBulkLoadHFileOk, if any
> WrongRegionException is caught and failures.add(p), then all the other
> IOException thrown by assertBulkLoadHFileOk will be ignored.
> so i think if (failures.size() != 0) {} should be dealt with after if
> (ioes.size() !=0) {}
> {code}
> for (Pair<byte[], String> p : familyPaths) {
> byte[] familyName = p.getFirst();
> String path = p.getSecond();
> Store store = getStore(familyName);
> if (store == null) {
> IOException ioe = new DoNotRetryIOException(
> "No such column family " + Bytes.toStringBinary(familyName));
> ioes.add(ioe);
> failures.add(p);
> } else {
> try {
> store.assertBulkLoadHFileOk(new Path(path));
> } catch (WrongRegionException wre) {
> // recoverable (file doesn't fit in region)
> failures.add(p);
> } catch (IOException ioe) {
> // unrecoverable (hdfs problem)
> ioes.add(ioe);
> }
> }
> }
> // validation failed, bail out before doing anything permanent.
> if (failures.size() != 0) {
> StringBuilder list = new StringBuilder();
> for (Pair<byte[], String> p : failures) {
> list.append("\n").append(Bytes.toString(p.getFirst())).append(" : ")
> .append(p.getSecond());
> }
> // problem when validating
> LOG.warn("There was a recoverable bulk load failure likely due to a" +
> " split. These (family, HFile) pairs were not loaded: " + list);
> return false;
> }
> // validation failed because of some sort of IO problem.
> if (ioes.size() != 0) {
> LOG.error("There were IO errors when checking if bulk load is ok. " +
> "throwing exception!");
> throw MultipleIOException.createIOException(ioes);
> }
> {code}
