Is your hbase deployed in a secure cluster ?
Here is signature for preGetOp:
public void preGetOp(final ObserverContext<RegionCoprocessorEnvironment>
e,
final Get get, final List<Cell> results) throws IOException {
User who wants this observer activated can pass attribute, with known name,
through Get object.
The observer can try to retrieve this attribute:
public byte[] getAttribute(String name) {
when attribute is present, do special handling.
FYI
