[TRAFODION-2272] Insure adequate hbase.client.scanner.timeout.period
UPDATE STATISTICS on large tables fails on some cluster installations
because the hbase.client.scanner.timeout.period setting is too low. The symptom
is that a sample scan fails with a SocketTimeoutException. This change adds
code to insure the setting is at least 1 hour.
This is viewed as a short-term fix. The setting is hard-coded in the
Trafodion HBase client code. Very soon there will be another change that will
abstract this out into some sort of properties file mechanism that is easier to
manipulate.
Too, as soon as we migrate to HBase 1.1-based distributions, the HBase
heartbeat protocol should eliminate the need for this particular change.
