It is possible to decrease the chattiness of the Phoenix JDBC driver
operating in HTTP mode?
We've tried using stmt.setFetchSize() but this appears to be ignored.
As it stands new we appear to be getting about 100 rows per POST which
presents a number of throughput issues when the results can be 10
Wrapping a thread-blocking call in a Future makes it asynchronous, but does
not turn it into a non-blocking call.

hi,all :

MapReduce,I got error:

HI,all
I create a table under phoenix and upsert somedata. I turn to hbase
client and scan the new table.
I got data like :
column=0:NAME, timestamp=1458028540810, value=\xE5\xB0\x8F\xE6\x98\x8E
I don't know how to decode the value to normal string.what's the
codeset?
Fantastic! Thank you!

Anil,
Do you know the name of the configuration in Cloudera Manager where I can add a
folder in the classpath of HBase? I’d like to use this configuration because
every time I update CDH the jar is deleted.

I figured this out, there was an old HBASE_CONF_PATH that pointed to a
non-existent path, so the hbase-site.xml file was not being used. Setting this
value corrected the problem. Simply point to the folder where the
hbase-site.xml file is located: export HBASE_CONF_PATH=/phoenix/bin/
Kevin
nline I’ve see suggestions to set the PHOENIX_LIB_DIR, but that has not
helped: export PHOENIX_LIB_DIR=/phoenix/bin/

That will solve my problem, thanks so much! Is there an upgrade path, or do I
simply overwrite the 4.1 jars with the newest jars and restart HBase?
