hbase - External table when queried from HIVE returns NULL for decimal datatypes -


i sqooped mysql table hbase , try create external table in hive.

i have column of decimal (38,1) in mysql moved hbase.

now while creating external table hive , while fetching records getting null values. remaining values arr string data type hive external table holds values.

while creating external table in hive data type used decimal(38,1).

any other solutions getting actual values in hive external table?

create table:

create external table namespace.tablename(c1 string,c2_col string,c3_col decimal(38,1),c4_col string)  stored 'org.apache.hadoop.hive.hbase.hbasestoragehandler' serdeproperties  ("hbase.columns.mapping" = ":key,cf1:a,cf1:b,cf1:c")tblproperties("hbase.table.name" = "namespace.hbasetablename");

remaining values fetched 1 column decimal (38,1) mysql moved hbase. hbase hive there mismatch column

sqoop serializes values hbase converting each field string representation (as if importing hdfs in text mode), , inserts utf-8 bytes of string in target cell.

since hbase holds data string format query trying find decimal, therefore getting null result. suggests create hive table string datatype , cast in decimal format during query.

example:

select cast('string_col' decimal(38,1)) string_col table;

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

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
