Lefty Leverenz commented on HIVE-15273:
---------------------------------------
Review of configuration parameters: Please make the parameter descriptions
more formal.
For example, for *hive.druid.http.numConnection* you could change "num
connection used by the http client" to "Number of connections used by the HTTP
client." For *hive.druid.http.read.timeout* you could change "read timeout
period for the http client" to something like "Read timeout period for the HTTP
client, in <units>."
Also, what does "PT1M" mean (as the default for
*hive.druid.http.read.timeout*)? Usually a time interval is specified with a
TimeValidator, for example:
{code}
HIVES_AUTO_PROGRESS_TIMEOUT("hive.auto.progress.timeout", "0s",
new TimeValidator(TimeUnit.SECONDS),
{code}
> Http Client not configured correctly
