------------------------------------
Summary: Clear cachedMaxVersions when setValue(VERSIONS, value)
called
Key: HBASE-14737
URL: https://issues.apache.org/jira/browse/HBASE-14737
Project: HBase
Issue Type: Bug
Reporter: James Taylor
HColumnDescriptor caches the value of VERSIONS in a cachedMaxVersions member
variable. This member variable should be reset or cleared when
setValue(HConstants.VERSIONS, value) is called, like this:
{code}
static final bytes[] VERSIONS_BYTES = Bytes.toBytes(HConstants.VERSIONS);
public HColumnDescriptor setValue(byte[] key, byte[] value) {
if (Bytes.compare(HConstants.VERSIONS_BYTES, key) == 0) {
cachedMaxVersions = UNINITIALIZED;
}
values.put(new ImmutableBytesWritable(key),
new ImmutableBytesWritable(value));
return this;
}
{code}
Otherwise, you continue getting back cachedMaxVersions instead of the updated
value.
