Thank you for asking @ABP. Cloudera doesn't have such a book. If you are wondering what to study for the CCA Administrator Exam (CCA131), you can find out on the certification page which lists:
Number of questions
Time limit
Score required to pass
Pricing
How the test is evaluated and scored
Audience and Prerequisites
Exam delivery and cluster information
Of course the part you would be interested in is listed as well in the Required Skills section. This section lists all the skills you will need to be able to perform as part of the test.

Hi @tuk,
Sorry about the delay on this. I contacted the certification team and found out that Cloudera Certified Specialist in Apache HBase (CCSHB) certification was retired. I am now inquiring about getting the document you linked to updated to reflect the change. Sorry for the confusion.

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

Of course I wondered what @KamaJinny was saying so I figured others may as well. Here is the translation via google translate:

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

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.
