aliyesami · ‎05-22-2019

In installing hive if I use the driver that came with HDP the DB connection test fails , but if I use the older driver I have(don't know the version) the check succeeds . [root@hadoop1 resources]# pwd /var/lib/ambari-server/resources [root@hadoop1 resources]# ls -al mysql-connector-java.jar lrwxrwxrwx. 1 root root 64 May 22 14:56 mysql-connector-java.jar -> /var/lib/ambari-server/resources/mysql-connector-java-8.0.15.jar [root@hadoop1 resources]#

I am trying to install apache drill 1.6 with HDP2.6 using the following GitHub rep but its not giving me any hosts to choose in "Assign slave" window, and when I click next it fails. is there a latest GitHub repository then the one below ? https://github.com/dvergari/ambari-drill-service

aliyesami · ‎04-03-2019

is it supported now in latest phoenix releases ? if yes any article or examples available ?

aliyesami · ‎04-01-2019

for a value of 99 , the hbase shows the key value as "\x80\x00\x00c" and for value of 1 in phoenix hbase shows it as "\x80\x00\x00\x01" how are these values generated? hex of dec 1 is 1 but what is "\x80"? also hex for dec 99 is 63 so how we get "\x00c" ?

without putting a trigger or extra column on the source table

aliyesami · ‎12-07-2018

can someone please advise ?

aliyesami · ‎11-30-2018

how can we bring updates into hive without loading the complete table and checking for the differences ?the incremental append will only look for a date column for newly added records and bring those records only.we can always create a trigger on the source table to create an additional record on any updates but whats the solution without having to create a trigger ? e.g lets say we have a table TEST (ID int , NAME string, LOGIN_TIME timesteamp) we do incremental appends using LOGIN_TIME colum so all new records will get moved to hive but what if someone modifies the NAME column ? how will sqoop pick it up ?
