Nick Dimiduk updated HBASE-6493: -------------------------------- Assignee: Nick Dimiduk Status: Patch Available (was: Open) > HashSet of byte array is being used in couple of places > ------------------------------------------------------- > > Key: HBASE-6493 > URL: https://issues.apache.org/jira/browse/HBASE-6493 > Project: HBase > Issue Type: Bug > Reporter: Shrijeet Paliwal > Assignee: Nick Dimiduk > Priority: Minor > Attachments: 0001-HBASE-6493-Use-custom-comparator-for-Set-byte.patch > > > While working on a jira I realized I had made a mistake of making a HashSet > of byte array. > Then out of curiosity I checked if we do same any where else in code base. I > came with following files. > # /src/main/java/org/apache/hadoop/hbase/mapreduce/RowCounter.java: > Set<byte []> qualifiers = new HashSet<byte[]>(); > # /src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java: > columnFamilies = new HashSet<byte[]>(); > # > /src/test/java/org/apache/hadoop/hbase/filter/TestFirstKeyValueMatchingQualifiersFilter.java: > Set<byte[]> quals = new HashSet<byte[]>(); > # > /src/test/java/org/apache/hadoop/hbase/regionserver/metrics/TestSchemaMetrics.java: > Set<byte[]> families = new HashSet<byte[]>(); > (1) and (3) are mine and I will fix them (not yet committed). Quoting the > exact reference from (2) below : > {code} > @Override > > public GetStoreFileResponse getStoreFile(final RpcController controller, > > final GetStoreFileRequest request) throws ServiceException { > > try { > > HRegion region = getRegion(request.getRegion()); > > requestCount.incrementAndGet(); > > Set<byte[]> columnFamilies = null; > > if (request.getFamilyCount() == 0) { > > columnFamilies = region.getStores().keySet(); > > } else { > > columnFamilies = new HashSet<byte[]>(); > > for (ByteString cf: request.getFamilyList()) { > > columnFamilies.add(cf.toByteArray()); > > } > > } > {code} -- This message is automatically generated by JIRA.
