I received a similar error, but for the LzopCodec (not LzoCodec) not being found.  In this case, I actually wanted to use the LzoCodec as my default compression codec (for legacy reasons...).   In order to get Hive working with Lzo on CDH 5.14.x, I did the following:   1) # Add GPLEXTRAS parcel to CM and distribute to all nodes: https://www.cloudera.com/documentation/enterprise/5-14-x/topics/cm_ig_install_gpl_extras.html 2) # Configure HDFS to use it: http://www.roggr.com/2014/06/enabling-lzo-compression-for-hive-to.html ClouderaManager -> Hive -> Configuration -> Service-wide -> Advanced -> Hive Auxiliary JARs Directory : /opt/cloudera/parcels/GPLEXTRAS/lib/hadoop/lib # Verify it works by invoking 'show tables' in hive with debug-logging enabled. There should not be any errors. The error condition if not working complains about LzopCode (not LzoCodec) not found. hive --hiveconf hive.root.logger=DEBUG,console 3) # Configure HDFS ClouderaManager -> HDFS -> Configuration -> Service-wide -> Compression Codes (io.compression.codecs): + com.hadoop.compression.lzo.LzoCodec + com.hadoop.compression.lzo.LzopCodec 4) # Configure YARN/MR2 # http://blog.cloudera.com/blog/2013/07/one-engineers-experience-with-parcel/ ClouderaManager -> YARN/MR2 -> Configuration -> SearchFor: compress -> mapreduce.output.fileoutputformat.compress: checked mapreduce.output.fileoutputformat.compress.codec: com.hadoop.compression.lzo.LzoCodec mapreduce.map.output.compress: checked mapreduce.map.output.compress.codec: com.hadoop.compression.lzo.LzoCodec   ...

Do not specify driver in sqoop arguments. Using the –driver parameter will always force Sqoop to use the Generic JDBC Connector regardless of if a more specialized connector is available. For example, if the MySQL specialized connector would be used because the URL starts with jdbc:mysql://, specifying the –driver option will force Sqoop to use the generic connector instead. As a result, in most cases, you should not need to use the –driver option at all.     Thanks, Ankit Gaurav Sinha ... View more

Thinks for bringing this up @AcharkiMed. I've seen this type of thing happen on other communities as well. While the view count is nice I also consider things like number of kudos and replies when guaging the popularity of a post. I'm assuming your concern is people thinking their post is popular when it could be them, or others, checking on it to see if there are updates. Am I correct?     If the reason for refreshing the page is to see if there is a new reply, I would suggest checking your subscription settings. I have mine set to notify me immediately of new activity plus I look often at the notification count on most pages.      ... View more
