Elliott Clark commented on HBASE-7221: -------------------------------------- So coming soon (HBASE-7012) most users won't have anything in hbase-server on their client classpath. With that in mind it, it seems like hbase-examples will actually have more visibility for people just starting out with HBase. (hadoop-examples seems like a great corollary here; more starting users read that code than hadoop-common) Also should this be renamed to something like CompositeRowKey so that the name isn't confused with a row key that is used inside the hbase-server ? > RowKey utility class for rowkey construction > -------------------------------------------- > > Key: HBASE-7221 > URL: https://issues.apache.org/jira/browse/HBASE-7221 > Project: HBase > Issue Type: Improvement > Reporter: Doug Meil > Assignee: Doug Meil > Priority: Minor > Attachments: HBASE_7221.patch > > > A common question in the dist-lists is how to construct rowkeys, particularly > composite keys. Put/Get/Scan specifies byte[] as the rowkey, but it's up to > you to sensibly populate that byte-array, and that's where things tend to go > off the rails. > The intent of this RowKey utility class isn't meant to add functionality into > Put/Get/Scan, but rather make it simpler for folks to construct said arrays. > Example: > {code} > RowKey key = RowKey.create(RowKey.SIZEOF_MD5_HASH + RowKey.SIZEOF_LONG); > key.addHash(a); > key.add(b); > byte bytes[] = key.getBytes(); > {code} -- This message is automatically generated by JIRA.
