# put

Put a file from a source path (local or remote), to a destination.

* Uses the newer openFile/createFile API calls and allows for a property file listing options to set on the createFile call.
* Prints IO statistics
* Supports the `-debug` mode for a low level trace of the network IO.

```bash
bin/hadoop jar cloudstore-1.6.jar put -options options -debug bin/hadoop s3a://target-london/hadoop
```

Here the options file adds a custom header to the object, and forces multipart IO on hadoop releases with
[HADOOP-19256.S3A: Support S3 Conditional Writes](https://issues.apache.org/jira/browse/HADOOP-19256) (Hadoop 3.4.2+).

```properties
# add a header, just PoC
fs.s3a.create.header.custom-header=value
# force multipart
fs.s3a.create.multipart=true
```
