Hi, i'm importing data from oracle db to hbase with sqoop. I used  sqoop line command, and all it's done.   sqoop import --connect jdbc:oracle:thin:@XXX:port/XXX --username XXX --password XXX --table XXX -m 1 --incremental lastmodified --last-value '2014-06-23' --check-column XXX --append --hbase-table XXX --column-family info --hbase-row-key XXX --hbase-bulkload  I tryed with oozie, and i have got this error in loop: INFO zookeeper.ClientCnxn: Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error) WARN zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect java.net.ConnectException: Connection refused  My cluster configuration is with 5 host: master,slave1,slave2,slave3, slave4 sqoop 1 client: slave1,slave2,slave3,slave4 zookeeper server: master,slave1,slave2 hbase server: hbaserestserver -> master hbasethriftserver -> master master -> master regionserver -> slave1,slave2,slave3,slave4 I have some doubt on my configuration: if my configuration is all ok, my question is: zookeeper server with localhost/127.0.0.1:2181 is correct to start? because i've got only 3 zookeeper server and i think this is my problem.   And there is some SQOOP_CLASSPATH or HBASE_CLASSPATH to set? oozie don't initialize everything? Thanks ... View more
