I have been having this problem intermittently as well. Did you find a solution? In my case, I found the following error in container log files: java.lang.NullPointerException at com.hortonworks.spark.sql.hive.llap.HiveWarehouseDataReader.close(HiveWarehouseDataReader.java:105)  Looking at HiveWarehouseDataReader.java line 105, it looks like this: columnarBatch .close() ; So I thought this might be missing a null check, and after adding the null check, problem is solved: if ( columnarBatch != null ) { columnarBatch .close() ; } Since Hortonworks has not been responsive to a previous pull request I created for spark_llap project, I'm not going to bother creating one for this. If Hortonworks/Cloudera care anymore about their code, they should be able to make a fix. ... View more

I finally realized this rounding is not done in hive, but in Zeppelin UI where I run my SELECT query which returns rounded result. There is an open bug for this issue: https://issues.apache.org/jira/browse/ZEPPELIN-1434 It is only rounding when showing on UI, so underlying data is correct. ... View more

Hive 3.1.0 rounds long integers stored as string

by Explorer in Support Questions

UPDATE: Issue occurs even when doing Hive SQL Insert: INSERT INTO test_ids SELECT "12345678901234567890" And the result is: 12345678901234567000 Original problem: I'm using hive 3.0 streaming to write string columns which are long numeric ids. Interestingly these numbers are being rounded so when stored, last few digits are being saved as 0. This is the famous JSON/JavaScript problem with numbers, but my data is string. Here is sample Scala code to reproduce: import shadehive.org.apache.hadoop.hive.conf.HiveConf import org.apache.hive.streaming.HiveStreamingConnection import org.apache.hive.streaming.StrictJsonWriter import org.apache.hive.streaming.StrictDelimitedInputWriter import org.junit.Assert val hiveConf = new HiveConf() hiveConf.set("hive.metastore.uris", "thrift://localhost:9083") hiveConf.set("metastore.catalog.default", "hive") hiveConf.setVar(HiveConf.ConfVars.HIVE_CLASSLOADER_SHADE_PREFIX, "shadehive") val writer = StrictJsonWriter.newBuilder() .build() val connection = HiveStreamingConnection.newBuilder() .withDatabase("default") .withTable("test_ids") .withRecordWriter(writer) .withHiveConf(hiveConf) .withAgentInfo("(my_test)") .connect() connection.beginTransaction() val rec1 = "{\"id\" : \"12345678901234567890\"}" connection.write(rec1.getBytes()) val rec2 = "{\"id\" : \"a12345678901234567890\"}" connection.write(rec2.getBytes()) connection.commitTransaction() connection.close(); 12345678901234567890 Value gets stored as 12345678901234567000, but the second value starting with character 'a' is saved correctly. Hive table is created as follows: CREATE TABLE `test_ids`(`id` STRING) Am I doing anything wrong? Or is there a workaround for this issue? ... View more
