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.

All I'm seeing are messages like the following when restarting haproxy: 2018-03-28T11:32:41-04:00 172.28.2.234 haproxy[26642]: Proxy main started. 2018-03-28T11:32:41-04:00 172.28.2.234 haproxy[26642]: Proxy static started. 2018-03-28T11:32:41-04:00 172.28.2.234 haproxy[26642]: Proxy impala started. 2018-03-28T11:32:41-04:00 172.28.2.234 haproxy[26642]: Proxy impalajdbc started. 2018-03-28T11:32:41-04:00 172.28.2.234 haproxy[26642]: Proxy main started. 2018-03-28T11:32:41-04:00 172.28.2.234 haproxy[26642]: Proxy impalajdbc started. 2018-03-28T11:32:41-04:00 172.28.2.234 haproxy[26642]: Proxy app started. And sometimes other messages like the following in the haproxy log - but they don't come in immediately after running an Impala query over JDBC such as from Hue or beeline: 2018-03-27T15:51:47-04:00 172.28.2.234 haproxy[4286]: 172.28.6.234:37768 [27/Mar/2018:15:51:47.621] impalajdbc impalajdbc/impalajdbc1 0/0/+0 +0 -- 2/2/2/1/0 0/0 2018-03-27T18:08:08-04:00 172.28.2.234 haproxy[4286]: 172.28.2.20:39978 [27/Mar/2018:18:08:08.888] impala impala/impalad1 0/0/+0 +0 -- 3/1/1/1/0 0/0 However, no logs come in when accessing from a BI tool such as Tableau using its native Cloudera Impala connector or the Cloudera Impala ODBC driver. Is there a way to increase the logging for haproxy so that we can know which Impala Daemon a query is executing on for the purpose of debugging potential issues of someone accessing from a BI application? I already have it said to debug under the listen section for impalajdbc. listen impalajdbc :21051 mode tcp option tcplog balance roundrobin log 172.28.xx.xx local2 debug server impalajdbc1 hdp104v.cmssvc.local:21050 server impalajdbc2 hdp105v.cmssvc.local:21050 Thanks, Braz

From the community knowledge article on how to setup the quickstart vm: 4. Some users have reported problems running CentOS 6.4 in VirtualBox. If a kernel panic occurs while the VirtualBox VM is booting, you can try working around this problem by opening the Settings > System > Motherboard tab, and selecting ICH9 instead of PIIX3 for the chip set. If you have not already done so, you must also enable I/O APIC on the same tab.

Thanks for following up @skamalj and congratulations on pasing your certification. As for the email address issue, I want to be sure, the certification team was made aware of it, no? I'm assuming so since your issue was resolved. 🙂
