Hello
I am trying to import data into Accumulo using this package. I have
truncated the code the log to make it relevant. As one can see login is
successful. I have been able to successfully invoke hdfs commands like `hdfs
dfs -rm -r -f hdfs://accumulo-hdfs-ha:8020/imports/custom_data_05222024 ` and
`hdfs dfs -put -f /imports/custom_data_05222024
hdfs://accumulo-hdfs-ha:8020/imports/custom_data_05222024`. Even getting a list
of Tablet servers works. However, invoking **importDirectory** fails with the
error below.
```
proxy_connection =
AccumuloProxyConnection(AccumuloProxyConnectionParams(hostname=proxy_host,
port=proxy_port))
with proxy_connection:
context = AccumuloProxyConnectionContext(proxy_connection)
connector = context.create_connector('accumulo', secret)
login = proxy_connection.client.login('accumulo', {'password': secret})
if login:
print(f"Accumulo login successful !!!")
else:
print(f'Accumulo login failed: {login}. Exiting...')
sys.exit(1)
client = proxy_connection.client
tservers = client.getTabletServers(login)
print(f'Tablet Servers: {tservers}')
print(f'Accumulo import directory: {table_name} {hdfs_dir}
{failure_dir} {True}')
client.importDirectory(login, table_name, hdfs_dir, failure_dir, True)
```
Log:
