>          Issue Type: Bug
>          Components: Compression
>    Affects Versions: 2.2.0

> 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
>   at org.apache.hadoop.io.compress.zlib.ZlibDecompressor.inflateBytesDirect(Native Method)
>   at org.apache.hadoop.io.compress.zlib.ZlibDecompressor.decompress(ZlibDecompressor.java:227)
>   at org.apache.hadoop.io.compress.DecompressorStream.decompress(DecompressorStream.java:91)

>   ... 43 elided
> Repeating the same with file created by:
> echo "abcdef" |  gzip > /tmp/a.gz 
> Works as expected
