impala vs hive 3 clarifications

APAI am about to upgrade from cdh to cdp and I have some questions regarding new version of Hive. Until now I used to have hive as etl service because it is more stable but slower than impala. My tables that bi users see are in impala. My questions are: 1) Is hive 3 fast enough to compete impala ? 2) In case of bi use is it more appropriate to point hive or impala(I read that hive 3 uses cache and makes bi repeated requests faster)? 3) In case of kafka flow, is it appropriate to create an acid table in hive 3 and store the fetched data live ? ...

Fetch missing ids from impala with sqoop

I have a table in impala and I want every day to check the source table with sqoop to see if there are any missing ids. For this purpose I have done: sqoop import to a staging table all the ids from the impala table select id from sqoop_table where id not in(select id impala_table) save the result to a .txt create a var and store the seded .txt in order to make the results from vertical to horizontal. From this step I have issues. When I try to parse this var in sqoop to fetch only the missing ids it throws me an error that argument is list too long. The thing is that I can not change the max capacity of vars. The average amount of ids for 2 days is 40k Is there any other way to compare the remote table with my impala table and fetch only the missing records? ... View more

Hi, I have some schedulers in OOZIE through hue and some of them some times fail. However when I run them manually after, they end successfully. Is there any way to put retry policy in my WFs?   Here is the error that I am taking: Exit code of the Shell command 1 <<< Invocation of Shell command completed <<< java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.oozie.action.hadoop.LauncherAM.runActionMain(LauncherAM.java:410) at org.apache.oozie.action.hadoop.LauncherAM.access$300(LauncherAM.java:55) at org.apache.oozie.action.hadoop.LauncherAM$2.run(LauncherAM.java:223) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1875) at org.apache.oozie.action.hadoop.LauncherAM.run(LauncherAM.java:217) at org.apache.oozie.action.hadoop.LauncherAM$1.run(LauncherAM.java:153) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1875) at org.apache.oozie.action.hadoop.LauncherAM.main(LauncherAM.java:141) Caused by: org.apache.oozie.action.hadoop.LauncherMainException at org.apache.oozie.action.hadoop.ShellMain.run(ShellMain.java:76) at org.apache.oozie.action.hadoop.LauncherMain.run(LauncherMain.java:104) at org.apache.oozie.action.hadoop.ShellMain.main(ShellMain.java:63) ... 16 more Failing Oozie Launcher, Main Class [org.apache.oozie.action.hadoop.ShellMain], exit code [1] Oozie Launcher, uploading action data to HDFS sequence file:  Stopping AM ...

Hi,   I run a sqoop import in order to fetch data from a table in sql server. Inside the sqoop I have a query which fetches every 6 mins data from 2 hours before until now. The weird thing is that sqoop doesnt fetch all the data. It is somehow random how many data it fetches. My sqoop command is the below. For example in this 2 hours scanning I fetched a record 28 times. 19 times all the rows were align with the  sql server but 9 they were half    sqoop import  --connect 'jdbc:sqlserver\ --username  \ --password-alias \ --num-mappers 10 \ --split-by an_int \ --fields-terminated-by '|' \ --query "select * from table where timestamp > '${offset}' and \$CONDITIONS" \ --delete-target-dir \ --target-dir    The amount of the data for 2 hours is ~800k ...
