Erick Ramirez created CASSANDRA-15679:
-----------------------------------------
Summary: cqlsh COPY FROM of map of blobs fails with parse error
"unhashable type: 'bytearray'"
Key: CASSANDRA-15679
URL: https://issues.apache.org/jira/browse/CASSANDRA-15679
Project: Cassandra
Issue Type: Bug
Components: Tool/cqlsh
Reporter: Erick Ramirez
h2. Background
A user was having issues loading CSV data with the {{COPY FROM}} command into a
{{map}} column with {{blob}} values.
h2. Replication steps
I can easily replicate the problem with this simple table:
{noformat}
CREATE TABLE community.blobmaptable (
id text PRIMARY KEY,
blobmapcol map<int, blob>
)
{noformat}
I have this CSV file that contains just 1 row:
{noformat}
$ cat blobmap.csv
c3,{3: 0x74776f}
{noformat}
And here's the error when I try to load it:
{noformat}
cqlsh:community> COPY blobmaptable (id, blobmapcol) FROM '~/blobmap.csv' ;
Using 1 child processes
Starting copy of community.blobmaptable with columns [id, blobmapcol].
Failed to import 1 rows: ParseError - Failed to parse {3: 0x74776f} :
unhashable type: 'bytearray', given up without retries
Failed to process 1 rows; failed rows written to
import_community_blobmaptable.err
Processed: 1 rows; Rate: 2 rows/s; Avg. rate: 3 rows/s
1 rows imported from 1 files in 0.389 seconds (0 skipped).
{noformat}
I've also logged
[PYTHON-1234|https://datastax-oss.atlassian.net/browse/PYTHON-1234] because I
wasn't sure if it was a Python driver issue. Cheers!
