title: how to read hdfs file with wildcard character used by pyspark
body: <p>there are some parquet file paths are:</p>
  
  <p><strong>/a/b/c='str1'/d='str'</strong></p>
  
  <p><strong>/a/b/c='str2'/d='str'</strong></p>
  
  <p><strong>/a/b/c='str3'/d='str'</strong></p>
  
  <p>I want to read the parquet files like this:</p>
  
  <pre><code>df = spark.read.parquet('/a/b/c='*'/d='str')
  </code></pre>
  
  <p>but it doesn't work by using <code>"*"</code> wildcard character.How can I do that? thank you for helping</p>
