Hello Matthew Jacobs, Adar Dembo, Kudu Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/4173
to look at the new patch set (#3).
Change subject: [java-client] Add ScanToken.stringifySerializedToken
......................................................................
[java-client] Add ScanToken.stringifySerializedToken
stringifySerializedToken takes a serialized scan token, and returns a
String suitable for debug printing. The string contains information
sufficient to determine which range of tablet(s) the scan token will
cover, and which rows within the tablets. Namely, the range partition
bounds and primary key bounds. Example output, wrapped for readability
(a, b, and c are column names with type STRING):
ScanToken{table=org.apache.kudu.client.TestKuduClient-1472595465767,
lower-bound-primary-key=(string a=1, string b=3, string c=5),
upper-bound-primary-key=(string a=2, string b=4, string c=),
hash-partition-buckets: [2],
range-partition: [(string a=0, string b=0, string c=0),
(string a=3, string b=5, string c=6))}
The Java client did not have any method of deserializing encoded primary
or partition keys, so most of the work in this commit is introducing
utility methods for that purpose. I haven't added tests of the specific
format of the strings, but I have added the printing to many of the
existing ScanToken tests in order to make sure that the formatting code
itself doesn't fail. I've also verified that the output looks good. The
format doesn't include information like predicates or consistency, but
that could be added in the future if so desired.
