preamble: I'm new to hadoop / hive. installed autonomous chaop, and now I'm trying to get the bush to work. I keep getting the metastore initialization error and can't figure out how to solve the problem. (hadoop 2.7.2 and hive 2.0)
HADOOP_HOME and HIVE_HOME A SET SET
ubuntu15-laptop: ~ $>echo $HADOOP_HOME
/usr/hadoop/hadoop-2.7.2
ubuntu15-laptop: ~ $>echo $HIVE_HOME
/usr/hive
hdfs works
ubuntu15-laptop: ~ $>hadoop fs -ls /

the hive does not work. says i need to initialize my metastor
ubuntu15-laptop: ~ $>hive
Logging initialized using configuration in
jar:file:/usr/hive/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Exception in thread "main" java.lang.RuntimeException: Hive metastore database
is not initialized. Please use schematool (e.g. ./schematool -initSchema
-dbType ...) to create the schema. If needed, don't forget to include the
option to auto-create the underlying database in your JDBC connection string
(e.g. ?createDatabaseIfNotExist=true for mysql)
so I'm trying to initialize it using postgres - but schematool is trying to use derby
ubuntu15-laptop: ~ $>schematool -initSchema -dbType postgres
Metastore connection URL: jdbc:derby:;databaseName=metastore_db;create=true

(state=42X01,code=30000)
org.apache.hadoop.hive.metastore.HiveMetaException: Schema initialization
FAILED! Metastore state would be inconsistent !!
*** schemaTool failed ***
so I modify hive-site.xml to use postgres drivers, etc., but since I have not installed drivers, it does not work
ubuntu15-laptop: ~ $>cp /usr/hive/conf/hive-site.xml.templ /usr/hive/conf/hive-site.xml
ubuntu15-laptop: ~ $>schematool -initSchema -dbType postgres
Metastore connection URL: jdbc:postgresql://localhost:5432/hivedb

*** schemaTool failed ***
so i try to use derby first move hive-site.xml again so default derby is used
ubuntu15-laptop: ~ $>mv /usr/hive/conf/hive-site.xml /usr/hive/conf/hive-site.xml.templ
