Subject Fwd: native snappy library not available when using count(distinct) grammar
Date Wed, 19 Mar 2014 02:31:49 GMT
getting the same error with the most recent phoenix v3.0

in order to fix had to add to incubator-phoenix/bin/sqlline.py:
    ' -Djava.library.path= /var/lib/hadoop/lib/native/Linux-amd64-64'+\

snappy binaries were installed
sudo yum install snappy snappy-devel
ln -sf /usr/lib64/libsnappy.so /var/lib/hadoop/lib/native/Linux-amd64-64/.
ln -sf /usr/lib64/libsnappy.so /var/lib/hbase/lib/native/Linux-amd64-64/.

 opened https://issues.apache.org/jira/browse/PHOENIX-877

Thanks for that info, Sean.
Mujtaba - we should add Snappy to the other jar as well. We use it for
compression for larger COUNT DISTINCT and other aggregates as well as to
compress larger ARRAY values.
