hadoop - Updating hive table with sqoop from mysql table -


i have hive table called roles. need update table info coming mysql. so, have used script think add , update new data on hive table:`

sqoop import --connect jdbc:mysql://nn01.itversity.com/retail_export --username retail_dba --password itversity \ --table roles --split-by id_emp --check-column id_emp --last-value 5 --incremental append \ --target-dir /user/ingenieroandresangel/hive/roles --hive-import --hive-database poc --hive-table roles

unfortunately, insert new data can't update record exits. before ask couple of statements:

  • the table doesn't have pk

  • if dont specify --last-value parameter duplicated records exist.

how figure out without applying truncate table or recreate table using pk? exist way?

thanks guys.

hive not operate update queries. have drop/truncate old table , reload again.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
