last_modifed_by and last_modified_time are properties that can change all the time. It's better to ignore those properties.

Thanks for the awesome script. I ran your script with my patch and most tables were able to run "show create table" with the exception of those tables that are not supported, i.e INDEX_TABLE, etc.: https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/catalog/TableLoader.java#L36-L37

Quick question, why are these added now? Don't see them in the show create output.

Patch Set 1:

I was curious to see if we'd see this anywhere else, and I ran the following against the minicluster. It looked to me that the only other category where "show create table" didn't work has reasonable "this is not supported" messages.

$(for db in $(impala-shell.sh -B --query 'show databases' 2> /dev/null | awk '{ print $1 }'); do for table in $(impala-shell.sh -B --query "show tables in $db" 2> /dev/null); do impala-shell.sh -B --query "show create table $db.$table"; done; done) |& tee /tmp/out

IMPALA-6571: NullPointerException in SHOW CREATE TABLE for HBase tables

This patch fixes the NullPointerException in SHOW CREATE TABLE for HBase
tables.

Testing:
- Moved the content of back hbase-show-create-table.test to
  show-create-table.test
- Ran show-create-table end-to-end tests

             :     HdfsCompression compression = null;
             :     String inputFormat = msTable.getSd().getInputFormat();
             :     if (inputFormat != null) {
             :       format = HdfsFileFormat.fromHdfsInputFormatClass(inputFormat);
             :       compression = HdfsCompression.fromHdfsInputFormatClass(inputFormat);
             :     }
I think these things make sense only for an HdfsTable (kudu format is handled below separately). So instead of checking for inputFormat != null, should we do something like

if (table instanceof HdfsTable) {
  // check for hdfs related stuff
}

I think we could merge this with show-create-table.test. Don't think we need a separate file for it.

cool, I didn't see those for hbase tables in my local cluster. Thanks.
