I'm using Flink to write CDC data to iceberg， and I'm using the master
branch.I came across the following problem.
`

`
When the Flink job is running, I start a spark job to rewrite data.This is
my spark code
`
RewriteDataFilesActionResult rewriteDataFilesActionResult =
Actions.forTable(sparkSession, table)
.rewriteDataFiles()
.targetSizeInBytes(TARGET_SIZE)
.splitLookback(SPLIT_LOOK_BACK)
.execute();
List<String> orphanFiles = Actions.forTable(sparkSession, table)
.removeOrphanFiles()
.olderThan(expireOrphanTime)
.execute();
BaseExpireSnapshotsSparkAction expireSnapshotsSparkAction = new
BaseExpireSnapshotsSparkAction(sparkSession, table);
ExpireSnapshots.Result result = expireSnapshotsSparkAction
.expireOlderThan(expireSnapshotTime)
.retainLast(30)
.execute();
`
Can someone help me see this problem？Thanks.
