Hi, at Exercise 4, there is a command: 4. Creating your collection solrctl --zk {{zookeeper_connection_string}}/solr collection --create live_logs -s {{ hostname }}   I am puzzled by {{hostname}} here. According the help of solrctl, -s should be followed by <numShards>. Do I miss anything here?   Thanks! ... View more

Hi, I got the following error when running: sqoop import-all-tables     -m 12     --connect jdbc:mysql://quickstart.cloudera:3306/retail_db     --username=retail_dba     --password=cloudera     --compression-codec=snappy     --as-parquetfile     --warehouse-dir=/user/hive/warehouse     --hive-importhist INFO hive.metastore: Connected to metastore. 15/07/24 14:49:16 ERROR sqoop.Sqoop: Got exception running Sqoop: org.kitesdk.data.DatasetExistsException: Metadata already exists for dataset: default.categories org.kitesdk.data.DatasetExistsException: Metadata already exists for dataset: default.categories at org.kitesdk.data.spi.hive.HiveManagedMetadataProvider.create(HiveManagedMetadataProvider.java:51) at org.kitesdk.data.spi.hive.HiveManagedDatasetRepository.create(HiveManagedDatasetRepository.java:77)   I guess the problem might be triggered by my previous running of the following command:   sqoop import-all-tables   -m 12   --connect jdbc:mysql://quickstart.cloudera:3306/retail_db   --username=retail_dba   --password=cloudera   --compression-codec=snappy   --as-avrodatafile   --warehouse-dir=/user/hive/warehouse   I have deleted /user/hive/warehouse, but it didn't help.  Any hint how to solve this? Thanks!   Hadoop321 ... View more
