>
> 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.
