Change subject: [java client] ITClient's new snapshot scanners can easily
timeout
......................................................................
[java client] ITClient's new snapshot scanners can easily timeout
This patch makes it so that a scanner timeout won't kill the test. It also
takes care of a typo in related javadoc.
The failure in question:
19:56:29.459 [ERROR - Thread-10] (ITClient.java:134) Got error while getting
row 260
org.apache.kudu.client.NonRecoverableException: could not wait for desired
snapshot timestamp to be consistent: Timed out waiting for all transactions
