it work now like this: first create the table from command line: /usr/hdp/current/phoenix-client/bin
./sqlline.py zookeeperHostname
create table test (mykey integer not null primary key, mycolumn varchar);
upsert into test values (1,'Hello');
upsert into test values (2,'World!');
select * from test;
and from RStudio like this:
conn <- dbConnect(drv,"jdbc:phoenix:lnxbig04.cajarural.gcr,lnxbig05.cajarural.gcr,lnxbig06.cajarural.gcr:2181:/hbase-unsecure")
query <- paste("select * from test")
B <- dbGetQuery(conn, query)
dbListTables(conn)
