[jira] [Created] (HIVE-17064) GZipCoded doesn't handle zip files
Andi created HIVE-17064:
---------------------------
Summary: GZipCoded doesn't handle zip files
Key: HIVE-17064
URL: https://issues.apache.org/jira/browse/HIVE-17064
Project: Hive
Issue Type: Bug
Components: Compression
Affects Versions: 2.2.0
Environment: OSX 10.12.5
Native Libraries
Hadoop 2.8 (Hive 2.2.0)
Reporter: Andi
Attempting to read a zip file using GZip Coded created by:
>echo "abcdef" | zip > /tmp/a.zip
fails, while the same gzip succeeds.
Code below is scala, run in spark-shell ( 2.1):
import org.apache.hadoop.io.compress.zlib._
org.apache.hadoop.io.compress.zlib.ZlibFactory.isNativeZlibLoaded(spark.sparkContext.hadoopConfiguration)
val in = new java.io.FileInputStream("/tmp/a.zip")
val gcode = new org.apache.hadoop.io.compress.GzipCodec
gcode.setConf(spark.sparkContext.hadoopConfiguration)
val giz = gcode.createInputStream(in)
val lr = new org.apache.hadoop.util.LineReader(giz)
val text = new org.apache.hadoop.io.Text
scala> lr.readLine(text)
java.io.IOException: incorrect header check

Repeating the same with file created by:
echo "abcdef" | gzip > /tmp/a.gz
Works as expected
