Subject Re: using MapReduce java.sql.SQLException: No suitable driver found for jdbc:phoenix occured.
Date Tue, 13 Sep 2016 20:29:51 GMT
[root@namenode phoenix]# findjar . org.apache.phoenix.jdbc.PhoenixDriver
Starting search for JAR files from directory .
Looking for the class org.apache.phoenix.jdbc.PhoenixDriver

This might take a while...

./phoenix-4.8.0-HBase-1.1-client.jar
./phoenix-4.8.0-HBase-1.1-server.jar
./phoenix-4.8.0-HBase-1.1-hive.jar
./phoenix-core-4.8.0-HBase-1.1-tests.jar
./phoenix-core-4.8.0-HBase-1.1.jar
./phoenix-core-4.8.0-HBase-1.1-sources.jar

add phoenix-4.8.0-HBase-1.1-client.jar
or phoenix-4.8.0-HBase-1.1-hive.jar(I'm not quite sure which one, you might
try ) to your classpath might solve your problem .
